Honestly, Zap and Lightning do need a nerf, but a less direct one since these changes would hit them super hard. A Zap as wide as a Rocket? Lightning change seems OK, but it was only buffed indirectly and should be nerfed indirectly, otherwise it might accidentally become trash again. 6 per cent is a lot for such a massive damage-dealing card.

Miner change would have to be accompanied with a stat buff, becuz remember the Bowler: Even when the stats are changed according to the new cost, that can still be a buff or nerf.
