Sifter Wurm's Aetherflux Invocation

Played this one a couple times at standard showdown. only won against a grixis deck that had basically the most expensive standard cards in it and didn't do my combo once. Just swung with the stomper and wurms, needless to say that player wasn't as good as the other's that I've played at the event. Lost all other competitive games but won a couple matches against U/W approach. Lost awefully to Ramunap red, which had rampaging ferocidon which is the bane to this deck, however after playing with the guy after I lost a few more times I managed to get a lifegain foothold and got ahead.Not necessarily that good, but once you get an invocation out and find a reservoir along the way it can sort of explode and you hit them for 50 asap. The stack crumbles. Resolve multiple invocation's and you'll be playing many cards, and if one of those is a Rishkar's Expertise you get to cascade all over again. It can be hard to keep track of at times. 20 land is pretty slim, but you definitely want to have a land enchantment in your hand at start or if not fogs to ensure you can do the combo at least and ramp into bigger things. Playing casually it's proven to be pretty fun and interesting.
