Tsalal Schemes: Mechanics

Chill: Whenever this deals damage to a creature, tap that creature. It doesn't untap during its controllers next untap step and receives 1 of this damage in the form of a -1/-1 counter. Used on 2 cards: Snow Flyer, Qys Glacierguard

Supposed to show cold and freeze stuff. Merging a wither variant with "tap and doesn't untap during its controllers next untap step" so show the cold is extra bad.

Variant A: This deals 1 damage per creature in the form of a -1/-1 counter. When it does, tap that creature and it doesn't untap during its controllers next untap step.

Variant B: Whenever this deals damage to a creature, tap that creature and it doesn't untap during its controllers next untap step. 1 of that damage is dealt in the from of a -1/-1 counter.

In card text or details pages, write the mechanic's code name (playtest name) between square brackets, like "[Crittercast]", "[Bushido 1]" or "[Delay 4 {2}{R}{R}]". It will be expanded to the mechanic's name plus reminder text, such as "Suspend 4 – {2} {r} {r} . (Rather than cast this spell from your hand,...)"
To expand a mechanic's name but not its reminder text, include parentheses at the end of the square brackets: "[Crittercast()]", "[Delay 9 {R}()]".
