Firebombs?

The play style of course depends on the draw. It can win by rushing the opponent with the fast cast infiltrate units.
It may also win off the fire bomb combo, which is to flood his deck with Fire Bombs using Light the Fuse and Flamebelcher. Use the Lumen Reclaimer to shuffle up the opponent's deck.

Of course all the infiltrate units can be triggered with Iceberg Scattershot.

The Wurmcalling is mainly used as a stall, but can be a finisher as well.

Thundering Kerasaur has some synergy with the Firebombs and Scorpion spells you force the opponent to draw with your infiltrators

Any input is well appreciated.
