Hish of the Snake Cult

A player with ten or more poison counters loses the game as a state-based action, even if no permanents with poisonous are on the battlefield.

For many playtest cards, you’ll need to make a generous assumption that basic game rules would be updated to allow them to work. The Mystery Booster 2 Playtest Card Notes section (reproduced here in individual Gatherer rulings) provides guidance for fitting these cards into the existing rules structure.

If a creature has multiple instances of poisonous, each triggers separately.

Once a creature with daunt has been blocked, reducing the power of a creature blocking it to 2 or less won’t cause that creature to stop blocking.

Playtest cards aren’t legal for play in any tournament format other than Mystery Booster Limited formats. On the other hand, we expect they will spice up a wide variety of non-tournament games (as long as everyone’s on the same page about using them!).

Playtest cards use a modified version of game symbols, such as {T} and {W}. These modified symbols should be treated as the standard symbols during play.
