Some monster calculate attack based on player deck and may be health. Sometimes there "bad" card in mods. StS count those card as overpowered and monster do enormous attack what kill player immidiately. For example I am just moment ago play Goldeglow mod and be killed by Hexaghost with second turn 36x6 attack. Day ago I am encountenerd same situation with Altegero mod. Card with description "do same damage to monster as they intended" raised enemy attacks drastically.

How StS calculated attack for those monster? Formulae?
