- On Straight+, increases ATK & DEF by 1.
Surprisingly enough, Leo's Shield is on par with that of several other GOD-rarity cards like Clover, Mun Mun, and Throne.
While his accuracy is a little bit lower (70% compared to other 75% AoE Shield cards), it's just as strong as far as Damage Reduction goes.
The stat buff is a pretty nice touch as well, not to mention the rarity of Red Shield cards in general.
Grants 15-35% Skill Boost when Main Card has Attack Skill.
However, there's also 33% Chance to apply a 1-tick Iron Wall.
While the Skill Boost is a bit random (and the Iron Wall fairly rare), Mogul Leo makes for a pretty decent Attack Sub.
Leo's Max HP just happens to be 2015 coincidentally.
