It should work fine. Just make sure you are using your monster, summoning a level 7, and that there are no restrictions placed on summoning. I haven't had any trouble with this, but then, I haven't used it in a while.
Could be good with the jins and sanga becuse you'll be able to use there ability's to stall for that one turn
(^_^) I just bought my third. Time to play with it.
I have not seen this explained yet. To use Tribute doll to special summon level 7 in same turn do this.
Set Tribute doll first in the magic zone, then summon a normal monster level 1-4. You can now activate Tribute doll, and you tribute the normal monster you summoned to special summon your level 7. MAKES A GREAT OPENING MOVE!!!
ALSO, This level 7 cannot attack this turn, BUT, special effects can still be activated.
EXAMPLE, I use this to special summon with double barrel dragon and activate the effect to destroy opponents monster same turn.
