The way I see it, you have the following main options, and thats outside of just upgrading the removal and finishers: Untapping Tokens Aristocrats +1/+1 Counters Big Spells So, lets go over a few of the options available to us and the cards I like, before going over my personal picks for upgrading
If this card is discarded to the Graveyard by a card effect: Special Summon this card from the Graveyard to your opponent's side of the field in face-up Defense Position
I'll post if there are any other updates
If you like Blood Moon, you can play a second copy of Blood Moon on a body with Magus of the Moon
If you really wanted to cover all the bases, you could add 9 more cards that, according to my research, are rarely but occasionally played competitively these days: Arrogant Wurm, Beetleback Chief, Bottle Gnomes, Fyndhorn Elves, Order of Leitbur, Order of the Ebon Hand, Portent, Shield Sphere, and Whispers of the Muse
The Wind-Up archetype might not be meta-relevant in the modern era, but if it ever returns, this card will be a core part of the strategy
