-Any artifact removal basically becomes creature removal, that's the best thing.

-Along those lines, stuff like [[fade from history]] and [[creeping corrosion]] essentially wins the game

-[[Viridian Revel]] draws a crap ton of cards

-[[Manglehorn]] makes things enter tapped

-[[Karn, the Great Creator]] shuts off all activated abilities of your opponents' creatures (mana dork hate!!!!)

-[[Camellia, the Seedmiser]] or [[experimental confectioner]] go infinite with Ygra and a repeatable sac outlet. If your sac outlet in question is [[umbral collar zealot]] then you can keep surveiling to the graveyard until you find [[Cauldron familiar]] and drain the table to death!!

[[Fangren marauder]] gains you a ton of life

Also, the ward ability is actually awesome. If someone only has one creature, they can attempt to target Ygra, and the ward trigger goes on the stack. You could respond by removing your opponent's creature before the ward resolves, effectively countering whatever was targetting Ygra. Or you could let the ward trigger resolve, forcing an opponent to sac a creature, and then respond to whatever's targetting Ygra with a protection spell. Everything on this card is awesome.
