Today's CotD is Excadrill from EP...well, best to think of it as a very poor man's Donphan Prime I guess. Statwise 110 HP is nice for a Stage 1, x2 Weakness to :water: is meh, -20 Resistance to :lightning: is useful, and :colorless::colorless: to Retreat is eh. Metal Claw deals a basic 30 for :colorless:, nothing fancy, and Drill Run is moderate at :fighting::fighting::fighting: for 80 and the effect of discarding an Energy off the Defending. So yeah...Donphan Prime pretty much outclasses Excadrill in everything, including cost, so if you don't want to put down the cash for him...well Excadrill is there I guess.
Modified - 2/10 (In terms of stats it's not bad, but it is utterly outclassed by Donphan Prime, who does so much more for pretty much the same costs along with better survivability)
Limited - 8/10 (Great choice for a :fighting: deck, big hitter in an easy to get out form)
Unlimited - 1/10 (No use here, just bad)
