Bug in game/card combo: Flash of Lightning and Unstable Evolution. Technically the echo’d Unstable Evolution played the next turn after Flash of Lightning should be free to cast but still costs 1 mana. Understandably this is unlimited mana that can turn every friendly minion into giants. Is the issue that Flash of Lightning activate at the start of the turn and thus not trigger for any cards added to hand/drawn; or an intended specific block to prevent infinite mana?
They nerfed echo’d cards so that they cannot cost 0 mana. I think the main reason for this nerf was abusing Snip-Snap combos if I remember correctly.
