You may want to hold that announcement, as I recall having received a "flyingtackleglomplickmolestwithdoublesommersaultandcan'tremembertherestbutitwascrazylong* Oh yeah, asterisk abuse for the win. xD
As for hidden treasure...well, they also get Barrel Behind the Door, Creature Swap (how about giving that there pillar to your opponent in attack position and smashing it? ;D), Prime Material Dragon/Rainbow Life (sorta, they at least turn the penalties to small boosts. xP), and the usual search and summon support that 0 Atk monsters enjoy (sangan, recruiters etc.). Then there was, I think, also that one card that lets you summon a monster from your hand to your opponent, though that may just have been an anime-specific fakie.
But yeah, pretty weak showing from the treasures as they're pretty much your average, uber-situational, weak set. Even so, they have inspired a set idea in me, though, so stay tuned at You Make the Card and don't you dare change that channel. ^_~
Before that, though, I think I'd better get to finishing that Armania IC; it's been hanging for far too long now. >.<
