Instead of going the lazy path and just doing a mirror match, this is what I came up with:

I'm assuming here that both players are aware of what the opponent's strategy is (which makes sense in a Bo5 war match, for example). In the first, blind match, AM kills quickly the offense of the grabboid deck, but on subsequent matches the grabboid player would switch strategy to keep grabboids unevolved, play one sword and keep the other swords and AW in hand, attempting to win by bursting damage, with shriekers and flown swords. The AM player would need now to outrush the slowed down deck. On his optimal strategy, the AMs are dead cards, but their threat must keep looming, so he must ensure he always has the quanta to play them. This means he needs to delay his damage a bit in the beggining to contain the much stronger damage of the grabboid deck. It ends up being then a race where the grabboids are causing damage more slowly but only need to cause ~60 damage to win, while the other deck deals damage faster but needs the full 100. With this new strategy, if it weren't for the dissipation shield, the scales would tip a bit in favour of the grabboid deck, however the shields make this matchup much more even.
I tested the decks playing 30 games against myself in Cygnia and got a 16-14 result, which is good enough for a 50-50 for me
For the depiction of the battle, since media was free I decided to make a paper and pencil drawing, since I hadn't touched that this Brawl (

Small story: After their scouts reported that the entropy army and their mercenaries were bringing antimaters, the generals of the earth-air alliance opted for using guerilla tactics taking advantage of some nearby ruins, wearing down the opponents with hit and run attacks using graboids. Finally it comes the time for the final attack which entropy's antimatters were powerless to stop, as shriekers stormed them and swords rained from the sky.
