Inspired by the way that people keep confusing convoke and conspire (both involve tapping creatures), and populate and proliferate (one increases tokens, one increases counters). Bonus points if your new mechanic's name is confusingly similar to two different existing keyword mechanics, such as "propagate".

I think it's probably going to be the most fun if your mechanic's effect is as different as possible to the existing keyword mechanic whose name it's similar to.

There are a few lists of keyword mechanics around the web. The Wizards Forums Keyword FAQ and Wikipedia appear to be some of the more up-to-date.

'Crash' produces Swimming Lessons and Explosive Salvo

Cyclic: Mistweaving Reflection

So Soulband Soldier doesn't count, then?

Hmmm. It's somewhat too similar to Arcbound Wanderer, but yeah, I'll let you have it for the name being just one letter away from one of the component abilities.

ROFL. That's a hilarious challenge! :)

­Myr Inforcer -- Infinity

­Phosphour Bolt -- Fourcast

­Banalish Cavalcade -- Flaking

Also Sludge Skeletons and Degenerate -- Degeneration

Okay, one more because I couldn't help myself. Piece of Loom -- Bifurcast

­Reach Leech -- Leech; got a couple more ideas on the way.

­Shatter Spot, Cave Chigger -- Swarm

I made March to Glory, Muffle, and Wealdborn Tracker.

Added the double feature Sarducci Lawman -- Showdown & Far Strike

Forgot to say that I added Goblin Tag-Team
