[Limited Edition KING]

[b]Synchro Resonance
Trap Card
Effect : [/b]During the Battle Phase select 2 monsters you control and send them to the Graveyard. Then Special Summon 1 Synchro Monster that has the same level as the combined monsters. At the end of the Battle Phase remove the Synchro Monster from play and Special Summon the monsters used for the Summon. This card can only be used once per duel.

Why only once per duel? And the effect seems too similar to Urgent Tuning.

It's only once per duel because it brings out a Synchro without a Tuner, and during any time. And then you get the monsters back.

Actually it says 'During the Battle Phase' meaning it can only be activated then. Not any time before or after the Battle Phase.

I just wrote 'once per duel' to limit it and balance it out.

What I meant to say was "either turn". And this card basically allows for an extra attack to be made that turn, so there's another thing.
