I agree we should be cautious about it, but I think it’s not that dramatic. Usually the eggs that do stay up are the ones that are ‘on curve’, like Kujata or Young Silithar. The opponents always make sure to go for the powerful ones first. (Also without fail, the Silithar Elder egg will spawn right next to the enemy general). The eggs that they can’t reach also usually can’t influence the board on the turn they spawn, even with rush. The only spawn where that’s an issue is Silithar Elder and those rarely spawn in the corner.
You always get one common, one epic, one rare and one Legendary minion with Chrysalis Burst. chances are if the enemy can only kill two or three, it’s going to be the legendary and the rare. (Vindicator/Silithar elder and Elucidator/Spirit Harvester/Unstable Leviathan) if the common is the only one that survived (unless you’re really lucky and got a Kolossus) you actually just played on curve or even lost some tempo (in case of young silithar or Phalanxar or Earthwalker) and the epics are Kujata, which is below curve and Makantor which, while strong, is easily dealt with if it doesn’t appear out of nowhere. I wouldn’t worry too much about it honestly.
Now it could be that this changes due to new minions being added into Chrysalis’ spawnpool, but so far we’ve only got one extra common which is below curve (Gro) and one rare which is always one of the ones destroyed (Mandrake). We’ll have to see what the future brings though.
I’m a bit biased since I’m a Magmar player but I don’t think this is as dramatic as some of the other spells and minions being played.
