You can, in the right decks, double the strength and defence of your entire battlefield presence for just five mana
With careful deck building, MDFCs increase both the number of lands in your deck (thereby preventing mana screw) and the number of spells in your deck (thereby preventing mana flood), which is incredibly powerful
the Rocky Helmet, which does 20 HP to the opponent's Pokmon whenever the active trainer takes damage
So far its been one of the single most impressive cards Ive cast, but that might just be because the format isnt entirely fleshed out and some decks are too rough to stand up to this kind of incredible efficiency
Despite the $96 market price offering a valid estimate of what you might pay for this card, the reverse holo caps out at $120 in NM condition and starts at $40 for a damaged copy
Still, it sold for somewhere in the region of $1580 regardless with the exact figure unknown due to a best offer being accepted
