Grenade Mech

 is a unit. It's a high health attacker that comes with 3 Pixies. It also has an Ability allowing him to build 3 Pixies by consuming one Blastforge.

Strategy
 is a rather situational unit. It is most useful against opponents with no access to good blockers and relying on breach-vulnerable attackers.

is not very efficient damage for its cost (though stronger than Base attackers when over Absorb), but it provides a large amount of pressure, with 4 attack on the first turn and the ability to sacrifice Blastforges for 3 more. 3 Pixies for 6 gold is a good enough deal that it often makes sense to continue clicking s and re-buying Blastforges.

Buying is mostly effective when you already have a large amount of persistent attack (e.g. from Tarsiers) to back it up, the spike in damage pressure can be overwhelming for an unprepared opponent. Starting with s will usually be ineffective since it costs just to get a single constant attacker (The starting Engineers defend earlier as well), however, it can be a strong counter to rushes such as a fast Savior (Only to be tried with good soak) or low econ red rushes as the opponent will not be able to defend adequately. The Pixies can also be saved to gain offensive finesse, making defending against s more annoying.

While has  Health, keep in mind it is not a blocker. Its high health, however, allows it to be breach-resistant though. It is also worth remembering that Apollo cannot kill.

Openings
Both player 1 and player 2 have fairly quick Grenade Mech rushes available. Just keep in mind that rushes are not a go-to strategy; instead they are useful mostly as a counter to an opponent  playing right into it, for example with a turn 2 Animus.
