mtg most complicated cards Magic: The Gathering” is officially the world's complex game Most Complicated and Complex Magic:

Whenever another Phoenix you control dies, you may cast Syrix, Carrier of the Flame from your graveyard

All that to say Cogsworth isnt invulnerable, but hes definitely a challenge to banish for your opponent, and makes your board a lot safer just having him around

Recouping part of the cost makes this more reasonable as a card that probably doesnt impact the board, though you can cascade immediately with the Treasure you generate

Put one of those cards into your hand

Obviously, this makes it a pretty good MTG card, as you dont have to spend your entire turn removing everything

A turn two Gang isn't even that game ending these days, there are loads of two and three drops that will hold that assault at bay enough
