I don't know much about Granblue, aside from the fact that they primarily operate from the drop zone. Well Thanatos appears to be the Granblue equivalent of Alice in Pale Moons. Both have very similar costs and restrictions on their skills, but some subtle differences can be found. First being the most obvious; Granblue does great work with their Drop Zone, so why would Thanatos ever go anywhere else, or search from anywhere else? The next, being the most important, and possibly overlooked due to being similar in almost every other way, Thanatos must hit the Vanguard.
Granblues, to my knowledge, make use of their Drop Zone in every way possible, and in doing so, have very fast, and reckless ways of getting cards into the Drop Zone. Captain Nightmist as one of them. With the ability to put one's entire deck into the grave in a matter of turns, there are bound to be some valuable cards one may need to retain. Thanatos can fish them out at the cost of a single counter blast.
Despite the fact that his attack, not only has to hit, but hit the vanguard, it can allow for more than 3 attacks in a turn, or revive a grade 0-1 to give another unit that extra boost it needs
Strategies and game play:
As stated above, it can pull out key cards from the Drop Zone and bring them into play allowing for an additional attack/boost. Such versatility is highly praised, but also feared. Your opponent would try to prevent this attack from hitting, if you had something lurking within your Drop Zone, or just to keep it at bay. Using this as a bluff to get your opponent to waste guard is an excellent maneuver, allowing smaller units to pass unabated.
Combos with other cards:
-From the same set, Storm Ride, Ghost Ship would be invaluable to have on Rearguard while Thanatos is attacking. Its natural 11k attack is already quite a feat, but when Thanatos' skill activates, it looses restraint as well.
-Captain Nightkid is able to quickly put valuable targets into the Drop Zone for Thanatos' skill.
-Captain Nightmist or units with similar skills may have put an unfavorable card into the Drop Zone when attacking, but that can be salvaged through Thanatos' skill.
Ways to counteract it:
-Similar to the Pale Moon's Soul Swap Style, this requires a bit of set up, and you can see what your opponent can do at present, making it easy to decide whether or not to guard. Guarding is the best defense against Thanatos until a Clan comes along that empties out an opponent's Drop Zone.
-Allows more attacks per turn
-Recycle Drop Zone
-Must hit VG for Skill
-Can't res himself
-Requires several moves (Not Turns. Actual Actions) before it becomes a viable threat.
-No other cards to perpetuate like Pale Moon
-Rearguard only Skill
Only the Double rare from Breaker of limits exists, however this skill bares a striking resemblance to The Pale moon Soul Swap Combo
Artwork and aesthetics:
Thanatos was a God of Death in Mythology, and the depiction certainly looks like a Death God. The skill doesn't reflect the name as well, however. For the Card of a Death God I'd expect some kind of skill to retire the opponent's units, and, going along with Granblue themes, send cards from the deck to the Drop Zone as a cost. Conversely, With a skill like this, I would think of a throw back to the Pale Moon, but that may be expecting too much.
I really do like the artwork, and the idea, but I'm not a fan of the fusion of the two.

I, myself, don't run Granblue, and the multiple attacks seem very impressive for a non-Dark Nation/Nova Grappler clan. I merely found it interesting as I browsed through my collection. I'd appreciate those of you who do run Granblues to find me out and tell me what I'm missing, as something does appear to be lacking.
