When playing with The Ooze, Doubling Season, and token generating permanents like Windkrag Siege, or Elspeth Storm Slayer the mutagen tokens can quickly outgrow all other tokens. For example I had one doubling season in play, two Windkrag Siege, and one The Ooze and one Elspeth Storm Slayer. So I was generating 8 goblin tokens at the start of the turn. I then used Air Temple and Elspeth to give them all +1/+1 counters which doubles from doubling season for a total of 4 counters each. Then my opponent wiped the board. The second time that happened I hit 250 mutagen tokens immediately during my opponent's turn. Now I was stuck because all of my creatures were generated this way. None would spawn so I couldn't use any mutagen tokens unless my opponent plays creatures. Even when they did play creatures and I would get another one or two out they would be removed and I'd be right back in the same situation. I assume in practice infinite token generation is an issue so limits make sense but I feel like there should be some wiggle room here so that getting unstuck is possible.
