Monster Reborn has been placed back on the limited list:
Target 1 monster in either player's Graveyard; Special Summon it.
Why has such a powerful card been placed back on the limited list? I'm not complaining because it is nice to be able to play it once again. But at the same time it is very easy to abuse. Especially since it's effect let's you snatch a monster from either player's graveyard for free. I mean imagine if someone used a card like borreload dragonBorreload Dragon and lost it. You could use Monster Reborn to take it from their graveyard.
So basically, like I said, I'm not complaining, but why would they limit such a powerful card.?
