Equalizers ruleset just as its name and images shows, it will turn the health of the entire cards (both sides) into equal value which is based on card with the highest health (before buff or debuff). It means having a high health card could turn into a double sided blade, it could rise up the health of both sides. Bringing low health card while maximizing other attribute might be the better strategy with the hope that opponent will be the one deploying the high health card.
