*Major caveat
Constructs generally want other constructs so here are some solid ways to construct constructs, with both commanders and non-commanders: Urza, Chief Artificer, Mishra, Eminent One, Vihaan, Goldwaker, Dollhouse of Horrors, Digsite Engineer, and Simulacrum Synthesizer
Like most other initiative creatures, you enter or advance to another room in The Undercity dungeon
and Smash, which can respectively deal two or three damage to a single character, Grab Your Sword is an effective way of whittling down enemy characters willpower before finishing them off with another attack or challenge - leaving the field open for you to quest your way to victory
Expect lots of players to dig for Boss's Orders to end games with Meowth EX
