is this tool for pokemon rumble blast?
No, it's a tool for Pokemon Rumble World,
The second successor to Rumble Blast (after the Wii U game succeeded it), and it doesn't allow importing -.-
It appears similar to the game, except there are micro-transactions that suck your
and legendaries are no longer 100% befriending. One can't even trade anymore!
Luckily, it seems that one can have more than Epic (or so it seems),
And SciresM may be working on importing Pokemon from Rumble Blast to Rumble World (not confirmed).
However, the editing tool for Pokemon was announced, so rejoice!
