Add to that the ability to chain together Glorious End after Glorious End to forestall your own death for a turn, and you have something pretty special
Cards similar to Inspiring Call include Make a Stand, Drudge Sentinel, Gaea's Gift
If some of the creatures are illegal targets as the chaos ability tries to resolve, the original distribution of counters still applies and the counters that would have been put on the illegal targets are lost
Especially in Sealed at the prerelease, if your pool includes enough fixing, dont hesitate to explore such a deck or even splash a fourth color
It can net us many cards and the fact that at II it let us tap up to two target creatures and put a stun counter on them, set up the minimum amount of draw to two cards which is a great starting point
For just two mana you can take an extra turn, which is incredibly good no matter what
