Change log:
I changed a rebalanced a TON of cards in this update, and I am pretty proud of the results. Other major changes include updating all of the mana rocks and Mega Equipment to the Tribal type they are associated with, both for flavor and gameplay reasons. I also reworked the Last Strike mechanic effects to prevent first strike damage, which carried over to how cards like Tsareena and Bruxish worked.
Changed a cycle of monocolor Normal creatures to Hybrid, so there are an extra 10 Hybrid normal creatures in the set, to reinforce the type's theme and ubiquity.
Blastoise was changed to actually be a Blue card. In fact, several Water creatures like Golduck, Crawdaunt and Pelipper were changed from non-blue effects to mill both to fit Blue's color pie and give mill a bit more viability as a strategy.
Reworked a lot of the "counters on creatures" effects to specifically affect +1/+1 and -1/-1 counters so things like the time counters from Perish Song couldn't be abused.
Removed the last of the six-sided die roll effects with Accelgor changing to an X-mana effect instead.
Fissure now targets creatures and Basic Lands to prevent the user from screwing the other player out of playing cards they drafted with a 1/720 Gym destruction effect.
