Yeah there was, but it's the next one in line. And with all the criticism this event is getting, i wouldn't be surprised if the devs made it a double event with summoning or something.

As for the double resurrect team, until you're able to 6* either Sleepless or Michelle, i'd stick with Queen as the tank. If we do the math, Sleepless dies twice, giving FS 30% more attack and 35% more skill damage. The same applies to Michelle. Swapping Sleepless for Das Moge means you will only miss out on 15% more attack and 17.5% more skill damage for FS. My point being is that queen is worth more than 15% more attack and 17.5% more skill damage for FS. Especially if you're able to take her through to 7* or 8* relatively quickly.

You see similar stuff to this all the time for auras. People swapping 8/9 heroes for 5/6in order to get a certain aura, when the units swapped out are often worth more than the bonus said aura grants.

tl;dr - Fusion event soon, swap queen for sleepless and lvl her ASAP, if you want double resurrect team, later in the game when you can upgrade Sleepless, put him back in
