1 - Double Colorless Energy We can't forget our favorite wild card ever since the first days of this TCG, since the Wizards of the Coast Base Set era, which had a lot of reprints for this card in future expansions, such as Heart Gold/Soul Silver, X/Y, and Sun/Moon
Great options include equipment like Lightning Greaves and Swiftfoot Boots, along with counterspells like Swan Song, Force of Negation, Counterspell and even Mana Drain
This removes what would have been the card's biggest strength, since Avian's 1000 attack won't defeat many monsters
The final chapter of One Ring to Rule Them All forces each opponent to lose life equal to the number of creatures in their graveyard, which can be pretty darn good if you've milled them enough
There are some older fakes and might be a few other fakes out there that don't have these flaws, but I'll cover some other general things to look out for at the end
