Mega Charizard Y EX stands out as one of the best cards in the game, due to its moveset
As you can guess with the decks legendary theme, all of the new cards are legendary, with two being artifacts and the rest creatures (side note: theres nothing in the deck that cares about legendary artifacts specifically, but a few cards that are affected by Historic spells, which includes all artifacts, and Dihadas minus ability looks for any legendary card)
Ally with Wyleth, equip him with arms, and draw tons of cards as you dispatch your opponents with martial superiority
instead of just being artifacts, all equipment cards are actually artifact creatures instead
Throw a potent card like [card]Purphoros, God of the Forge[/card], into the mix and suddenly Norin becomes a clock for the entire table
And unlike Gishath, Ghalta can be built for reasonably cheap
