slime cards mtg Green (The token has no counters and isnt monstrous.) Art by James Paick Age Group MTGNexus - King Slime

This is one of the strategies that I foresee growing stronger with each new set release, but doesnt quite make the cut for competitive gameplay in its current state

There is a limitation to what you can make here

Fumarole and Needle Spire are potent cards and even Hissing Quagmire does some useful stuff and yet they all seem to be regarded as weak

Especially in the Commander format, blink-focused strategies helmed by commanders like Brago, King Eternal are remarkably popular and powerful

If you choose the first and/or second modes but all of the targets become illegal before Mystic Confluence resolves, the spell won't resolve
