First off, "Traditional Deskbots" is another way of saying "Bad Deskbots". You're setting aside more fruitful and stronger fields with a far more versatile deck in favor of putting on the blinders for a simple battle-based OTK.
Second off, it's not good for that either.
I feel like you don't understand what Iron Draw does. It sounds like you think it just limits it to Machine summons for the rest of the turn or something, so let's go over what it does in more layman's terms:
If the only monsters you control are exactly 2 machine effects monsters, draw 2 cards, then for the rest of the turn you only get one more Special Summon (though that single Special Summon can be multiple monsters).
Let's consider that basic combo you keep touting as good: you summon 003, bring out 002 and get a search. Now if you were wanting to activate Iron Draw, this is when you do it as you're most likely to get it off. But if you wanted to go further, you would use those two monsters for Genius, then use Guitaars to bring out Miccs. Then you can use it now, get a draw 2, then...
You have one more special summon, and assuming this play all goes well, you have one more normal summon and one more special summon. You CAN go into 003 again and bring out another 002, then you have 4 monsters with some decent stats, but that's it. That's all your field is, and that field is weak and asking to be destroyed.
Alternatively, you can Pendulum Summon monsters, but again all you're doing is bringing out bodies with stats. Going first, this is an unacceptable field that won't accomplish anything in stopping your opponent, and going second you'd have to be going against a fairly incompetent deck for that to actually work to your benefit.
My argument that you can't use this with Saryuja or Beast isn't because "But it works on machines", it's because after your limited window of using this card you do not have enough Special Summons to actually be able to go into one of those monsters.
You say this isn't "like duality", but it really is, because honestly I don't think you know how this card works. Leaving you with only one Special Summon and two monsters on the field leaves you with nothing. It's a terrible field, and I doubt you've actually mapped out when this can be used where it's not going to be just a dead card in the hand and actually benefits you to some degree.
It doesn't matter what variant you're using, Iron Draw is a bad card for Deskbots, and arguing to me that you can potentially use it in an inferior variant doesn't suddenly make the card good (even though it's bad for even that).
just OTK's, yet i mention infinity and genius in the same comment. you've misunderstood me again.
"I feel like you don't understand what Iron Draw does. It sounds like you think it just limits it to Machine summons for the rest of the turn or something,"
tell me, can you activate machine draw with any non machines on the board? no. the deck in question is deskbots right? yes. deskbot pendulums restrict you to deskbot pendulum summons correct? yes. you only get one summon after using machine draw correct? yes. now under that context, what non machine monster based board are you imagining me using this with? If your board is not machine based, the card is dead as doornails, which is why i restricted my examples to machine type ED monsters. because non machines prevent it from triggering, and summoning any non machine type ED monster after using it (at least on that same turn) is highly unlikely. don't misinterpret practical examples as ignorance of card text. it does not limit you to machines only, but summoning anything but machines greatly reduces the opportunities to use it, as non machines prevent you from accessing it.
minor example time:
Normal 03, special 02. search 06, machine dupe 02, search 01 or 03 depending on the board you face, or another scale if needed, (if you need no scales, then just get 01 and 03), turn the 02's into gaia saber, activate 06 and any other scale (preferably the 08, save 05 if you have it), branch off here depending on what you have:
1)wavering eyes if you have it to search another scale, use 06 to get back 03 or 02 (02 if you want search stability, 03 if you want to end it this turn) activate scales, activate iron draw, draw 2, if you drew bots, you're golden, if not, it's likely another searcher or the field spell, pendulum 2-4 monsters, beat face for game via one of the 03 boosting your 01 by 2k to 4.5K (if not 7.5K) and a field of gaia saber, 03x2, whichever deskbot you summon from the ED, and the 01. that's a game field, and defense is almost irrelevant due to having put at least 06 or 08 into the ED while having three 02 in grave (in other words, either a 2k double swing with two 03's backing it, or switching a defensive monster to attack position with a 01 staring it down and two 03's backing that). yes, it's basic brutality, but it still has enough damage on board, and versatility from the ED, to end the game turn 2, and Battle protection is rare enough for that to actually matter. machine draw is the card right before the last burst of power is about to hit the field.
2)activate iron draw, draw 2, this is the hand without wavering, so the cards you searched would be 03 and 01 pendulum all of the above two you picked, and the same scenario as above presents itself, with about 2k less damage overall. still enough potential damage to break a field of strong monsters, and you can swap out the 01 you search for either the 08 or 09 depending on the situation.
next scenario, assuming you have an 05 in hand as well, normal 02, dupe, seach one 05 and any other scale, turn 02 into genius, activate any scales but the 05's, pendulum two 05, search with genius, pop two S/T if you can, (if either scale is 06, hit that one to recoup an 02) do the infinity thing, machine draw for two, set something and either swing or pass.
I can make more scenarios up for you if you want. iron draw isn't a new star to the deck, it's something to add in and test out. there's even more wierd OTK things you can do with needlefiber and the new cyber dragon should you choose to splash those in, but this has already been long enough, and those aren't out in america, so i'm excluding them for now
i'm not advertising this as the greatest thing since sliced bread, but it annoys me to see things get tossed aside without diving deeper into how you can play around them down the line. not every card is a sleeper hit. but iron draw, as a draw two, is arguably prime material for such a case if ever there was any. exploring what you can do with it is far more productive than just saying "it can't work here" and instantly trashing it.
deskbots are versatile enough that the pure build can pull this off. i've been playing them since they came out, i've built and rebuild the deck multiple ways. grind game deskbots can put out amazing damage suddenly, and can build very quickly. iron draw is not that hard to find uses for in the deck. and for the love of all that's holy, stop misinterpreting my words.
