I'm not sure where I was really going with this card, I just put some ideas into a card and here's what came out, so yeah, basically it's a card that encourages you to use multiple Types in your Deck, throwing in Machines and Fiends for maximum potential, as it allows you to easily activates its effect that blows up all monsters on the field with other Types than it, which it change. You can't use it as a material, unless you use the same Types and you can only control 1.
2 monsters with different Types
If this card is Link Summoned by using a Machine or Fiend monster: You can Special Summon 1 monster from your hand. Once per turn: You can target 1 monster this card points to; this card’s Type becomes that monster’s Type, then destroy all other monsters on the field with different Types from this card. If you Link Summon using this card, all the other monsters must be the same Type as this card. You can only control 1 “Metamorphosmachine”.
