They dont really synergize with the rest of the deck, apart from Timin being a Spirit, but they would make for a very interesting pair in the command zone

The other thing I found with evolve guys is that it makes you want to curve really awkwardly and consequently makes you lose tempo and mana efficiency
These days it sometimes sees some fringe sideboard play in Eternal formats, but other than that its just collectability
No matter how perfectly built your deck is, mana issues are inevitable, but to give you a rough idea, I would say that when you run the numbers, anything over 85 percent for the early game is reliable
Piling auras like Daybreak Coronet and Ethereal Armor onto Xenk will quickly turn him into a giant attacker
