Can These Cards Form an Infinite Combo?

Asked by DemonDragonJ 2 weeks ago

If a player controls Doubling Season, Crystalline Crawler, and Marath, Will of the Wild *f-etch*, can they generate infinite mana, or will that not be possible?

Can you please explain the process you're looking at?

I see something like this:

Setup: Crystalline Crawler and Marath, Will of the Wild each have three +1/+1 counters with Doubling Season in play.

  • Remove a counter from Crawler to add a mana, let's say . Crawler has two counters.

  • Use that to activate Marath for X=1, choosing to put a +1/+1 counter on itself. Marath has two counters.

  • Season doubles the counter, so two +1/+1 counters are put on Marath. Crawler has two counters, Marath has four.

  • Remove a counter from Crawler to add . Crawler has one counter.

  • Use that to activate Marath for X=1, choosing to put a +1/+1 counter on Crawler. Marath has three counters.

  • Season doubles the counter, so two +1/+1 counters are put on Crawler. Crawler has three counters, Marath has three.

So that just puts you back where you started.

  • Season doubles the counter, so two +1/+1 counters are put on Marath. Crawler has two counters, Marath has three.

  • Use the other to activate Marath for X=1, choosing to put a +1/+1 counter on itself. Marath has two counters.

  • Season doubles the counter, so two +1/+1 counters are put on Marath. Crawler has two counters, Marath has four.

So that just puts you back where you started, but you moved a counter from Crawler to Marath.

  • Remove a counter from Crawler to add . Crawler has one counter.

  • Use that mana to activate Marath for X=2, choosing to put a +1/+1 counter on itself. Marath has two counters.

  • Season doubles the counters, so four +1/+1 counters are put on Marath. Crawler has one counter, Marath has six. Removing any more counters from Crawler would kill it, so the combo stops.

I'm not going to brute force any more numbers, but I don't see an obvious path to infinite mana. The most positive net effect I see using those three cards is shuffling counters back and forth between the two creatures.

legendofa, thank you for your explanation, and I am glad to know that, before I attempted to actually execute such a combo in an actual game.
