, , Put a verse counter on Yisan: Search your library for a creature card with mana value equal to the number of verse counters on Yisan, put it onto the battlefield, then shuffle.
Yisan is a mono-green toolbox engine: each turn you pay and tap to add a verse counter, tutoring a creature with mana value equal to the verse count directly onto the battlefield. You climb the verse curve to assemble ramp, value, and combo pieces in a precise order, snowballing into either an overwhelming board or a deterministic loop.
Repeatable, untargeted creature tutoring straight to the battlefield every turn
Lets you build a toolbox deck with one-of silver bullets fetched on demand
Resilient engine that can rebuild after wraths and grind value in long games
Enables tight, scripted combo lines by fetching pieces at exact mana values
Telegraphs your plan and is an obvious removal/tap-down magnet
Slow without untap support since it activates only once per turn at sorcery speed
Mono-green means little interaction and no protection from counters or stack tricks
Vulnerable to graveyard/exile hate and stax pieces that punish creature ETBs or tutoring
