confirmed, though the savegame is corrupted and lots of bugs :
- Sometimes activating
Pyrokinesis directly ask you for a red card for alternate cost even if you have enough red mana generating land, if you hit cancel the "no target" tag will appear on the previously activated
Pyrokinesis. If you have several
Pyrokinesis in hand and keep doing that eventually all
Pyrokinesis will be tagged and AI will ask for 4R mana instead then 3GG.
- Sometimes
Pyrokinesis ask for 3GG instead of 4RR if you don't have red cards in hand but enough red mana generating land

- After you pay all the mana required, the game will ask you to select a creature 4 times which are the 4 damages that are redistributed, which can be troublesome if you lost count of target selected (there should be a counter like 1 on 4, 2 on 4 like
Fireball)
- The "no target" tag stay during the whole game, making the alternate cost impossible to choose unless another card than
Pyrokinesis is choosen (you can still pay for mana)
