You may choose new targets for the copy.) Spell redirection (Change the target of target spell and/or ability with a single target.) Stealing permanents, permanently Switching power/toughness "Time Walk" (Take an extra turn after this one.) "Transformation" (Target creature becomes a color/card type with N power and N toughness.)

Some of these lists include Water Energy and Energy Switch to attack with Radiant Greninja (and possibly Cancelling Cologne), adding an additional threat: now, even decks relying on one-Prize Pokmon, like Gardevoir and Lost Box, must have Manaphy in play or Roaring Moon can take a game-winning lead

A tournament circuit launched earlier couldve captured more of that initial interest
Sacrificing an artifact doesnt mean too much, especially since you usually use that artifact to cast this spell
for example, a card with three 9.5 subgrades and one 9 may receive a final 9.5 or 9 depending on which categories are weaker
