Flying, trample
Whenever Hellkite Tyrant deals combat damage to a player, gain control of all artifacts that player controls.
At the beginning of your upkeep, if you control twenty or more artifacts, you win the game.
If you don’t control twenty or more artifacts at the beginning of your upkeep, Hellkite Tyrant’s last ability won’t trigger. If it does trigger, it will check again when it tries to resolve. If you don’t control twenty or more artifacts at that time, the ability will do nothing.
