EVO emblems were basically non-existent until finally they weren't. I got 22 of them in the grand theft event that just concluded. Don't burn them just to burn them, but if you've got a general who you expect to be an active part of your team for a long time, go ahead and use it.

Here comes the platinum priest event, which means it's finally time to burn all of those tickets I had been saving. I had saved up:
168 silver tickets
253 gold tickets
15 platinum tickets
36 soul tickets
105 SSR Takeda Shingen tickets

Mostly that's by not using any tickets for the last three weeks, though a lot of the Takeda Shingen were from an older soul ticket event that I was just waiting for the next platinum priest event for.
