Getting more powerful with every Ally creature cast could make this a force to be reckoned with
I had fun trying to beat the decks that people had spent $400 armed only with my cheap deck, but eventually I arrived at the point where there was a card that was strictly better than another card in my deck and I would need to replace it if I wanted to really have good odds of winning
For example, when Boon-Bringer Valkyrie enters the battlefield, you can either put a +1/+1 counter on Boon-Bringer Valkyrie itself, or you can put a +1/+1 counter on another creature and have that creature gain flying, first strike, and lifelink until end of turn
The most overpowered cards are powerful and unfair
