So I haven't used sleep that much at first, because in our game usually there is someone near who can wake the creature next turn. But recently I started to wonder if it is more useful than I think if I pair it up with other cards. I would like to ask if my ideas are valid or not:

-if I put retaliate on an enemy sleeping creature, than a friend hits him, what will happen? Rules say when he gets damage, the sleep turns into daze. Would than the woken creature attack its friend depending on daze throw? Would be fun to sleep a buffed enemy this way.

-would a block on enemy creature block his friends first attempt? (also does block card block attack spells?) If yes, than you disabled an enemy, and wasted an enemy attack, could be good against enemy mage + 1 big creature.

-I could see reverse attack working as well if the enemy only has big hitters

-my last idea could be pricey, but what about sleeping a big enemy than teleporting him away from friends? (behind your lines or to an other corner) This could disable the big enemy and an additional creature for some rounds until they go there and back (except if the enemy uses an attack spell).

So my main question is are these ideas (the first 3) valid by the rules? Also, could they be useful, or are they way too expensive for some wasted actions and some friendly damage?
