Grumbo Abundance

I'm still trying to find the best shell for the package of Praxis Adept, Gemblazer Cannon, and Malaga Amphitheatre. This particular shell is a go-wide aggro list with payoffs in Grumbo, Tota Legend and the old favorite Abundance.
The Praxis Adept package gives the deck the possibility of very powerful starts. For example:
T1: Praxis Adept
T2: Malaga Amphitheatre -> +2/+2 on Adept -> Swing (4 power) -> Grumbo -> Grenadin Drone -> Raging Jackal
Or:
T1: Praxis Adept
T2: Gemblazer Cannon on Adept -> Swing (3 power) -> 3 drop
T3: Swing Adept -> Dump hand -> Abundance
Most of the other cards chosen are low-cost units that draw more cards or play more units. A notable exception is League Explorer. This is a flex slot, and I just chose it for being a cheap aggressive creature.
My burn spell of choice is Searing Strike. It cleanly answers Darkwater Vines, and is also strong against onis. The fact that it is often "free" helps to have good abundance turns as well.
Suggestions are welcome. I just added Inferno Phoenix to the market, because I felt I needed another threat, and I haven't tested it yet.
