I literally have no experience with Morphtronic monsters or Link monsters, but here goes nothing.
FIRE / Link-2 / ATK 1900
[ Machine / Link / Effect ]
N / S
1 or more "Morphtronic" monsters
• If an Attack Position monster is Linked to this card: "Morphtronic" monsters, "Power Tool Dragon", and "Life Stream Dragon" you control gain 600 ATK. Also, this card can attack your opponent directly.
• If a Defense Position monster is Linked to this card: "Morphtronic" monsters, "Power Tool Dragon", and "Life Stream Dragon" you control gain 600 DEF. Also, "Morphtronic" monsters cannot be destroyed by battle or card effect.
Next Up: 2 or more Union monsters
You did fine; no worries about it. (All you need to know about them is: SPAM EQUIP CARDS and do something with Power Tool / LSD; but yeah, anything will do for them at this point because Rua.dek really sucks now)
Link 2 - WATER - Aqua/Link/Effect
SW / SE
1 or more "Penguin" monsters
You can use the (2) and (3) effects each once per turn.
(1) This card gains 200 ATK for each "Penguin" monster on the field. (2) You can Tribute 1 "Penguin" monster; destroy 1 card your opponent controls, then if the Tributed monster was linked to this card, you can destroy another card your opponent controls. (3) You can Special Summon 1 "Penguin" monster from your Deck linked to this card.
1 [or more] "D/D" monsters
(Because hell knows how much these things got screwed over because Konami changed the field)
