Right now, there's only, like, four battles that have abilities worth protecting from
This monster has 3750 attack points (even stronger than Blue Eyes White Dragon) and the duelists use cards like Fairy Meteor Crush to deal piercing damage
Speed Wing, a four-energy attack, deals 120 damage, and with three colorless energies required, it's not hard to power up
It also has the ability, Explosive Heat Dash, which removes Entei's Retreat Cost if it has any Fire Energy attached
Take Takeno's Cavalry, a 1/1 for 4 mana that can tap to shoot an attacking or blocking Spirit for a mighty one damage while swinging for one itself (unless its blocked, and then you get a 2/2 for our 4 mana investment)
