Gigantomancer + Exuberant Firestoker

[RetroRebel]

Help me out here, would these two work together? I mean would the creature still be a 7/7 as Exuberant Firestoker is triggering?
Thanks

Edit: Gigantomancer (just so it can also be seen, heh)

Hello.

So this combo would still work. Gigantomancer's ability lasts until your turn ends. The end step, despite the name, comes before the very end.

The end step is split into two parts. The part where things can be activated, and the cleanup step, where everything goes back to normal.

This article on Wizards should help you out. https://blogs.magicjudges.org/rulestips/2011/04/at-the-beginning-of-the-end-step-vs-until-the-end-of-turn/
