I think people are over thinking this update too much and not testing quite enough. I have not been grinding at all, I have only been playing on the beta trainer and I can tell you right now, the only card that is really OP is SoPe. If you happen to get 2 supernovas in your opening hand, and 2 SoPe and 2 entropy towers or pends, plus w/e else, that is like 11 cards in your first turn, some of which you might be able to play right away.
All the cards that received changes are not affected as much as everyone is whining about. They are working just fine for me. Mind you this is against the AI, but that is fine. The game vs other players will be far more interesting with the changes. They are not game breaking changes, but they are sufficient enough to get people to start thinking about other uses for cards and using other combos and cards they never use. Suck it up, I've tested, and approve of all the new cards and changes.
Immolation/Cremation - fire still has the fastest start out of any element, and you can still get 3 destroyers out first turn with 2 cremations
Ash/Ash - now 0/5 instead of 0/7, so now it takes 2 attacks to kill it instead of 3, while most other creatures are still only 1
Deflagration/Explosion - cost increase by 1 for upped and unupped, still cheaper than steal, and its fire, remember the first card I talked about, ya, still fast PC
Schrödinger's Cat/Schrödinger's Cat - no one uses it anyway, good buff?
All the shards are fine now. I tested before, commented, they were changed, tested, they are better, more balanced. SoS is a gamble in conventional decks, but could be used in some creative ways. SoPa slows you down for a turn, so unless you use a few at a time, you will only slow yourself down on multiple turns. Obvious use is fractal and scorpions, but try a water deck with flooding for the +4/+4, 5/5 squids is nothing to gawk at.
