So... I just read this:
"Other powers redirect a game effect (usually damage). When an effect is redirected, the
target of the effect changes from its original target to the new one chosen as described in
the game text, even if that target was not a legal one for the original effect. The source of
the effect remains unchanged from the original." - D&D Rulebook pg 19
And we are aware of what Storm - Weather Witch's global does:
"Global: Pay [1 Mask] . Change the target of an action die that targets a character die to the character die of your choice."
So.... Options:
Casualties: Basic Action Card
2 cost
"KO target Sidekick.
** KO an additional target Sidekick if able.
Global: Pay or . Gain 1 life whenever an opposing Sidekick is KO'd this turn."
Play casualties, use Weather Witch to redirect the effect from a sidekick to ANY CHARACTER DIE.
This strategy also works with Mirror Force: Basic Action Card, the difference is just a choice of globals.
Vibranium Shield: Cap's Protection
5 Shield
"Place this die touching your target character. It does not go to your used pile. You may place this die in the used pile at any time to prevent all damage to the character for the rest of the turn.
Global: Pay to prevent 1 damage to a character or player."
Play this targeting your ... anything, then redirect it to you opponent's Green Goliath to prevent him from going off with the Hulk-splosion.
These were the options I found, got any others?
