It can read as "heal by 1-2 each of your allies, they all attack with overkill this turn. Ignore all retaliate or forced response". In the late game you can finish the game with good tempo: at 2ER, this card will spare you 5-6 consequential damage, helping you keep the pressure on. It is the team training of aggression, without tempo issues.
Tempus can stick around for the right card to cancel while still delivering value. Shark-Girl, Sunfire will feel like cheating in the mid game, milking those low cost 2ATK allies. Wolverine, Colossus will be machines without their 2 consequential damage. Boot Camp, Brute Force and Enraged will sing. Around turn 5, this card will allow to ditch 12 to 15 damage that you wouldn't be able to do due to consequential damage or retaliate.
It finds a home in heroes that can skip the chump blocking, like Rogue, Iceman, Nightcrawler, Magneto, Storm...
