Mr. Sarpadian, I need your request: I want to build a budget Simic deck with a tempo-based aggro style but keeping mechanics like Evolve, Flash, among others. I would like to use the new Bouncing Krasis and the deck will be to play fun and informal games outside competitive formats. Thanks and sorry for the inconveniences.
The Evolve deck is more an aggro deck than a tempo deck, but once you have a critical mass of evolve creatures you want to have spells that control the battlefield.
One-drops are key, so you definitely want to run four each of Experiment One and Cloudfin Raptor. Two-drops are also key, so Gyre Sage and Shambleshark are necessary as playsets. Don’t be afraid to just cast a Shambleshark during combat on your turn to evolve your one-drop.
Three-drops are next. The two that shine are Bounding Krasis, a terrific tempo play that evolve all your other creatures, and Renegade Krasis, which will evolve your one- and two-drops while still being evolved by a Bounding Krasis too.
Few plays are as crushing as playing a Cytoplast Root-Kin to evolve a Renegade Krasis and then plop an additional +1/+1 counter on every creature you control. Experiment One into Shambleshark into Renegade Krasis into Cytoplast Root-Kin is 6+6+5+5=22 power on turn four.
Simic Charm (unsurprisingly) does everything this deck wants to do. It makes a creature huge, bounces an enemy creature to keep up tempo (That’s two kinds of removal!), and protects your krases from spot removal.
That’s most of a deck right there. Playsets are recommended for consistency. You generally want to curve out nicely every game. Good luck!
