How is the demon + master + altar infinite?

You need to cast master, it ETB and creates 3 creatures, sacrifice tokens and master with altar, You get and 4 energy counters (cuz 4 other creatures died this turn), activate the reanimation ability of Demon, return master to the battlefield, one black mana is still floating in the pool. Repeat!

I feel stupid now... thanks for clearing it up!

Always glad to help! :)

So many combos.... This deck would suck to play against... at the very least it is a great list for a ton of combos. I wish I could loop the +1.

Thanks a lot! Very grateful for upvote!

I might try some of these loops in my decks

Sure, some of them could fit pretty good in black or coloreless decks.

Is this budget?

For now, the deck is in constant change, and is a WIP. And it contain a lot of expensive cards and cards that I don't own (so it's not budget right now), rather it is a list of cards to be collected in a potential deck. It will be a lot more testing and description changes later.

i was joking... it costs about 1500 dollars
