Just remembered that there is definitely something other you can play with tentacle...
those nasty saruman condition that became minion(not quite usefull as saruman won't be near, not throne to pump them, at least not in a tentacle deck)
and the most viable ones.. if you are short of minion in that moment, and they are flooding just use
A Shadow Rises... throw them in and use when/if you want, as Watcher tecnically (because i assume noone tried yet on Gemp to do that) don't discard them as they are still condition and not minions.
