Using my current deck I get far less use out of this than I wish I did. It's a great card for tribute summoning and/or getting a effect monster out immediatly. It's great at what it does, but the condition for its activation is far too tricky to execute more than once (at best).
Great effect, but not convinient enough for my current setup. In general I'd recomend Double Summon over it. Maybe Super Double Summon with or instead of this would make a difference? (that may actually work...)
I'll come back for you one day when I know better, Herc.
