Re-Fusion and Blue Eye's Twinburst do not work together.

[Flanatic]

I played one of the matches using a Blue-eye's deck; used Polymerization to summon Blue-Eye's Twin Burst Dragon. Several turns later I tribute it to summon a regular Blue-Eye's White Dragon expecting to be able to summon Twin-Burst back with Re-fusion sitting at 3700 LP.

Re-fusion would not activate, nor become able to activate for the rest of the duel.
Any idea's what went wrong?

Text of Twin Burst :

"Must be either Fusion Summoned, or Special Summoned by sending the above monsters you control to the GY (in which case you do not use "Polymerization")."

This is probably the reason but I'm not sure.

If i'm not wrong, Twin Burst cannot be summoned by Re-Fusion, because of the text: Must be either Fusion Summoned, or Special Summoned by sending the above monsters you control to the GY (in which case you do not use "Polymerization") and using Re-Fusion does not count as a Fusion summon, so none of the conditions are met.

That probably is the condition needed for it; thank you both for clearing this up.

lol, they sell it in new deck now, would it be bugged?

"Select 1 Fusion Monster from your Graveyard, Special Summon it,"

there are many "Fusion Monsters" which "Cannot be Special Summoned" and "Must be Fusion Summoned"
