Since sigils scale with your highest level creature and gene strength, is there a good way to beat high level sigils?
So far all I can think of are ( none of them are particularly good):
Have an army of level 1 GS 1 creatures
Some sort of crazy speed focused build
Some sort of HP build+Woe (if they kill your nether, they die before they can kill anything else)
Spamming dark transformation on your nether doomsday spectre-manticore decimator-humanitas santus at start of battle
Just stacking items, nether upgrades, cards, spellgems, perks, etc like crazy to make up the 10X difference
Getting damage reduction 90+ and somehow killing your opponent
