Grimble has a use in mono for a couple of reasons -
- Crit up elemental link
- Quintus/C Quintus/any other slow purple
Running him against tel teams I usually try to let Tel fire first, which then means that I will charge up C Quintus and after C Rig, Grimble, Tiburkiss, and C Quintus the enemy is down 2, 3 or 4 heroes. Proteus mops up the left overs. Doing this means that I really only charge up C Rig and Quintus but at this stage I don’t need to charge up any others. He does charge himself too though so that’s nice.
I do find him a bit more useful in a 4-1 stack where he is my insruance policy against a bad board of my red tiles. Good reds = win. Good purples = charge up reds = win. I would take him against Tel + 1 summoner, preferably Freya or Bera as they are fast. It is possible to dump tiles into Freya to make her charge twice and basically then charge everyone up on my team
