I have been playing around with a pet deck in Arena Standard which can generate infinite mana and unlimited card draw, but the effectiveness of doing so has been stymied by games being forced to a draw or me being forced to cease drawing cards and generating mana by Arena's "stall protection". It seems to believe that no progress is being made in the game state, even though I am continuously drawing cards and developing my field, as well as generating enough mana to cast a way to close out the game.

The specific cards I am using are Agatha's Soul Cauldron with a Sleep-Cursed Faerie exiled by it, two or more copies of Badgermole Cub in order to generate infinite mana -- all creatures that can tap for mana with +1/+1 counters on them, such as a land animated by Earthbending, will tap for [X] plus [G] for each instance of Badgermole Cub, and can then untap themselves for [2] using Sleep-Cursed Faerie's activated ability, adding one mana to the pool each time --

And Stormchaser's Talent and Boomerang Basics to draw an unlimited number of cards -- [U] to cast Stormchaser's Talent, [3U] to return Boomerang Basics to hand from the graveyard, [U] to cast Boomerang Basics targeting Stormchaser's Talent, drawing a card in the process, which can be repeated indefinitely thanks to generating unlimited mana --

Which can be then done until a finisher, usually Craterhoof Behemoth or an arbitrarily large Goldvein Hydra can be drawn and cast.

I recognized that there are severe downsides to using this strategy on a digital client compared to playing in paper -- in paper play, I could simply demonstrate that the mana generation loop is indeed a loop, have my opponent acknowledge it, and say I repeat the process until I generate an arbitrarily large amount of mana, compared to having to click through the abilities manually for each iteration of the loop -- which cannot reasonably be solved due to the limitations of said digital format.

However, I believe the game being forced to draw in the case of the mana generation loop is not a reasonable result. As long as additional mana is being added to a player's mana pool and has ways to spend it, the game state is progressing, not being stalled. I would appreciate if an affordance for situations like this was made in Arena.
