As seen by the results of not only this tournament and also Klinklang at US Nationals, decks that can move Energy around to abuse Max Potion and can freely retreat between Pokmon are very strong
Shaman can shuffle back "Ashened" cards in the GY or Banishment and can search out Obsidim, while Spearhead can tribute itself to bounce back a monster the opponent controls--provided they control any monster that has 2800 or more ATK (coincidentally the same ATK Veidos has)
Although it has now finished, it is the best Ive played
Dialga 62 Rotom Lightning 70 Assault Laser (20+) If your opponent' active Pokmon has a Pokmon Tool attached, this attack does 30 more damage
There are multiple cards in color with Ashiok that are going to love to use those exiled cards for various powerful effects, like Wasteland Strangler or Ulamog's Nullifier
If this banished card is returned to the Graveyard: Add 1 Level 4 or lower Zombie-Type monster from your Deck to your hand
