You can summon a Blue-Eyes Ultimate Dragon by using Summoner of Illusions's effect to tribute another monster on your side of the field. However, Blue-Eyes Ultimate Dragon will be destroyed during the End Phase on the turn that it was summoned this way.
.....you know Yugioh has a 5 zone gameplay in real life, right
Besides, it's fine in DL since a normal Fusion Summon allows you to use monsters in hand as material anyway, so it's not like you have to summon the BEWD.....
Regardless of all the BS yal writing the ultimate dragon has one hell of an entrance and it will make your brain freeze for a moment, whether is going to get destroyed or not but the feeling of seeing its entrance conclude all ya SHT.
At the very least you should replace the 3 random 1900 Normal Monsters with 3 copies of Reload. (It doesn't interfere with Heart since you can use it in the Draw Phase, and can fix dead hands/continue a Heart that stopped at Fusion Gate.) Also, the Gem-Knight Fusions are better for this purpose than the weak ones you're using.
