So I've done several practice matches, and I found the strategy to be pretty good, but it's hard to tell without someone good to test against. I made a video on a few matches of using the strategy against a few high points people:

After making this video I cleaned it up a bit more and now I'm pretty good with it. It's also pretty strong from this particular tournament (fast AP regen). Right now I'm not sure what I like better, hildy or gilgamesh, as gilgamesh allows me to spend like a bunch of minion points on something else, but hildy allows me to protect the tech units from an opponents ball of atk buffed minions.

The weakness is that spreading out is a bit harder since your ball isn't as mobile and requires a lot of summoning points to support. Mandy spam on the left and right is actually harder to deal with than usual. If you set up and take the centre, you can use hildy to run to the sides and use the lb, then run back and cleanse. Also if the opponent rushes before you can set up the combo it can also be difficult to work with.

This might be the next top tier strat, but I also think that it may be so good that it needs some more effective counters. Running 4 gilgamesh into a ball and exploding seems like a good counter, as well as traps. The apkallu's range ability might work too. A group of apkallu's is already very deadly since they are so tanky.

In the future, they need to add a spell cancellation minion, something that creates a bubble around your minions for 10s or so that causes all abilities to be removed for both you and the opponent. Or maybe a minion that sets all AP points to 0 fieldwide, or prevents abilities for 10s fieldwide.
