Zirda, the Dawnwaker is a nifty little card
The deck features 3 copies of Yorvo, Lord of Garenbrig, which is already a very strong creature at 4/4 for 3 mana, but also gets stronger each time you cast a green creature (and all your creatures are green!) The deck adds 3 copies of Thunderous snapper, which is already a 4/4 for 4 mana, but also draws you cards each time you cast big creatures
This also means there isnt much reason to put our commander into the graveyard should it die, since we dont get its cast trigger if we cheat it into play by some other method
It does unfortunately cost 6 mana, but itll only cost if you can get it into the graveyard via dredging another card or some other efficient route
Wheel of Fortune has the advantage of filling your graveyard and enabling discard payoffs, while Timetwister nerfs graveyards
It doesn't have to be your own character, either
