High Alert

[heloirf]

"High Alert" is affecting opponents' creatures.

High Alert
{1}{W}{U}
Enchantment

Each creature you control assigns combat damage equal to its toughness rather than its power.
Creatures you control can attack as though they didn’t have defender.
{2}{W}{U}: Untap target creature.

Damn, I thought it was just a simple typo in the new StaticFilter (getPlayerPredicate() should be getControllerPredicate()) but it's a deeper problem. @xanderhall 's rework in #11068 probably should have added a few more test cases (well, ideally some tests would have existed beforehand). The inner combat method useToughnessForDamage calls filter.match with two arguments instead of four, ignoring controller predicates in the filter.

I think I'm going to split off another class CombatDamageByToughnessControlledEffect to handle the filter copy logic and add the ControllerIdPredicate like the old effect did, and add a warning to each about predicates being ignored.
