2 minion.
First minion: 66% HP, AMF to base decay counter level, VA as needed, SG all remaining. AoI BoF, TSA NSCs CoI.
Second minion: Mostly HP, with the exception being BL to 1/4 ST. ToA Exbow MH, TGs EBs AoM MgS.
Offers two damage types, 60% (assuming no DM) lifeleech to break GA easily even without all the HP, plenty of HP for raw survivability, allows the use of MgS on a high HP minion and an exbow to compete with big tanks. Minimal DM vulnerability.
Seems good to me assuming a fairly level MPR playing field.
Most of the credit for this goes to Nat.
