I understand, SG. I was merely making a claim for Congeal, and I understand exactly why it isn't overpowered, but I guess if playing the devil's advocate isn't allowed, then I'll just post what I really think, which is that Supernova, not Congeal, is overpowered. It allows for Rainbow decks to get a huge burst in quanta in order to play the cheap, effective cards.
Another argument can be said about Elite Otyugh. When Sundial came out, Zanzarino also changed Elite Otyugh from a 0/4 for three Gravity to 0/5 for four Gravity. I really don't know why he did this, as it's actually a much better creature this way, able to eat Silurian Dragons and Ulitharids with no help. Otyugh is one of the most powerful creatures in the game, and should be brought down to 0/4 for 3 quanta again (or even 4 quanta) probably.
