I always pretty much disregarded the Megamorph card (double attack if your LP is lower than opponents, halve it if yours is higher) but in a duel today in the game I was playing, the opponent brought out Buster Blader (2600ATK/2100 DEF) and was murdering me. I had a Monster Reborn I was saving, but no monster that was strong enough. I finally drew Megamorph, and it was at a time where I still had just enough LP to be above my opponent, so I equipped the Megamorph on his Buster Blader, lowered the attack to 1300, Moster Reborned a Neo the Magic Swordsman, and proceeded to whoop some...pixels.
