Slimefoot Combo Calculator

This is a damage / trigger calculator for a Slimefoot-based commander deck in Magic the Gathering. There are a few parts to this combo:

• Slimefoot, the Stowaway (the commander) can create Saprolings (1/1 green tokens) for 4 colorless as an activated ability.
• Ashnod's Altar, can sacrifice said Saprolings to generate 2 colorless mana.
• Slimefoot deals 1 damage to all opponents and heals you for 1 every time a Saproling dies.

It goes like this: you pile up a bunch of Saprolings, sacrifice them to the altar, get mana, deal damage, heal, create more Saprolings, repeat. All of this happens at instant speed. Once it starts, it's nearly impossible to stop. If someone reacts to this process, you can simply react to them and continue.

That's the base loop. There's plenty of stuff in the deck that can tweak that. Some cards let you create Saprolings on the cheap, some give additional effects on Saproling death or on sacrifice.

The following is a calculator that simulates the combo. You put in how many Saprolings you start with, how much they cost to create and how long you want the simulation to go on for. That last setting is important when the cost of creating a Saproling is less than or equal to 2 since the combo goes infinite. It then tells you how long it goes on for, how many times Slimefoot was triggered and how much mana you have left at the end of it. You also get a table that shows you the simulation round by round.
