Gawain gets to keep his 1.4*1.3=1.82 Buster buff for 3 turns instead of 1, and when he isn't using Buster cards, he's still getting a 1.4 general damage buff almost on-par with a 1-turn Monstrous Buff steroid (i.e. Kintoki, Gorgon) that lasts 3 turns. And since Gawain has a BBB deck and his damage buffs are on a 5 turn cooldown, he'll be doing stupid amounts of damage for 60% of the turns that he's fielded.
