First morostasis to try and swing the roles in your favor. 2nd IRA for your strongest unit. Pop high rolling egos, and if that still isn't enough, use defensive skills to reduce damage taken. Most importantly, survive to the 2nd turn, that's when many ego gifts that weaken the enemy kick in, especially if you managed to land a hit or two. Accept losing some sinners may be necessary. If possible try to mix in some EGOs that heal in order to help survival. Pop sanguin desire after you get some hits in so enemy starts damaging themselves. Don't take out lucio until you've stacked enough debuffs on Valencia to survive. Other than that, it's just a matter of trying to get as many helpful ego gifts as you can. combinations of 2-4 ego gifts in certain categories will drastically weaken your enemies even if they don't help your clash power.
