This box is not bad at all actually.
It boosts E-heroes who already received support thanks to Spunky Jaden event, elemental hero CORE cleans your opponent's field and it's pretty easy to summon tornado with miracle fusion. Not bad really, they could have added Tornado in a Big Box but they didn't. I like that.
The other day I watched a video from Playmaker and the guy summoned 3 tornadoes in one turn thanks to Miracle Fusion.
This Box ain't bad at all, yeah and Stun Trap is really OP; I thought they were going to release it as an UR card, so I'm pretty satisfied.
