1 Tuner + 1 or more non-Tuner monsters If this card is Synchro Summoned: It gains 800 ATK for each card currently in your hand. When this card you control is destroyed by your opponent's card (by battle or by card effect) and sent to your Graveyard, if all the monsters that were used for the Synchro Summon of this card are in your Graveyard: You can Special Summon all of them, but their effects are negated. You can only use this effect of "Ascension Sky Dragon" once per turn.
Burnborg Jet is my “use a lv2 tuner with opponent’s Lava Golem to get rid of it and become a synchro monster”. But now I’m not sure if this guy should replace it... it’s much stronger, but against burn decks, Jet’s self-destruct effect is better.
Ah, that's very nice then if it only counts the amount of cards at the time it was summoned.
If this was a level 7 or 8 synchro then I would consider adding this to my decks. But as it's a level 10 it's kinda expensive to summon for a 3000 defense monster, as you will need at least 3 cards in your hand to get a decent attack.
Might I suggest phantom hand infernity's?
Phantom Hand negates any discarding if used properly, and since there are multitude of level 8 synchros, getting to ASD isn't too difficult. The only difficulty being sustainability.
nice artwork and generic synchro, but unfortunately the effect is not too good.
