By the name, I first thought it was a Blackwing synchro and got all excited, but I was wrong. But of course, the card itself is much related to Blackwings.
Wind/Winged-Beast
Synchro
Effect/5/2100/700
1 Tuner + 1 or more non-Tuner Winged-Beast Type monsters
When this card is destroyed and sent to the graveyard, you can Special Summon 1 level 4 or lower Winged-Beast Type monster from your deck.
It kinda is a no brainer that this card was meant for Blackwings, or even the new archetype, Dragunities.
I really thought the promo would be somehow related to Six Sams, but I guess Konami wants to keep their prices for the new Sim Samurai staples.
The card basically dies in order to search out something for a bigger cause. For example, it can special summon Phalanx for Dragunties, in order to synchro summon.
I wouldn’t exactly say Vortex the Whirlwind is “fast” but it can summon out support cards a lot faster. (especially desirable tuners.)
I don’t think playing 3 Vortex in an extra deck is necessary for Blackwings but 3 for Dragunities, since their main objective is to send monsters to the spell and trap zone, and then instant synchro.
