I am looking for help with reviewing sets and/or maintaining Lore Seeker and the Big Custom Box. If you're interested, please contact me in #general in the Custom Standard Discord. —Fenhl
Tap an untapped creature you control: Put a climb counter on that creature. Activate this ability only any time you could cast a sorcery.
Creatures with climb counters on them don't untap during their controllers' untap steps.
At the beginning of your upkeep, if you control ten or more creatures with climb counters on them, you win the game.
