It's Anime Matsuri again!! YAYYYY!!! On another note, several clans have gotten Legion during this event(see: "Legion: the basics"), and one of them is Angel Feather with their beautiful Celestials. Let's take a look at their Legion unit shall we?
Holy Edge Celestial, Malchedael
[ACT](VC): Legion 20000 "Overdose Celestial, Asmodel" (If your opponent has a Grade 3 or greater Vanguard, only once, this unit may return 4 cards from your drop zone to your deck, and search your deck for the specified card, and perform Legion)
[CONT](VC): During your turn, if this unit is in Legion, all of your units in the front row get [Power]+2000. Then, if you have a face up card in your damage zone with the same name as a unit on your (VC), all of your units in the front row get [Power]+2000.
[AUTO](VC): When this unit attacks a Vanguard, if there is another unit in the center column, this unit gets [Power]+3000 until end of that battle.
Overdose Celestial, Asmodel
[AUTO](RC): [Counter Blast (1) & put this unit into your damage zone]When this unit's attack hits a Vanguard, you may pay the cost. If you do, choose one face up card not named "Overdose Celestial, Asmodel" from your damage zone, and call it to (RC).
I don't know about you guys, but these 2 just makes AF even more fun than it already is. Looking at the G2 Legion mate, it's an easy way to achieve the 2nd part of the skill for Malchedael. It can also combo with Emergency Celestial, Danielle when it enters the damage zone, allowing for more attacks in a single turn. Asmodel is basically a very pressurizing unit which would force your opponent to guard if they don't want more full-strength attacks coming their way(Raguel and Danielle, I'm looking at you :P).
Now let's talk about the G3 itself. Although this might seem a little weaker than Zerachiel in terms of all-round field power, the Vanguard power is absolutely devastating. Let's take a look: 23K(when attacking) + 4K(first part of skill, adding 2K to each unit on VC) + 4K(second part of skill, adding another 2K to each unit on VC) + 9K(possible boost from Hesediel with Zerachiel in the damage zone)= A devastating 40K Vanguard attack
Comparing to Zerachiel with a maximum consistent attack of 26K per turn, this unit obviously outclasses Zerachiel in terms of Vanguard power alone. Run this in an 8 Crit build, and it's a hell lot of pressure. :D
I'll go into a basic pressure field setup for this unit:
Left column: Asmodel(front row), Hesediel(back row w/ face-up Zerachiel in damage zone)
Center column: Legion Malchedael + Asmodel(front row), Hesediel(back row)
Right column: empty front row, narelle/hesediel in back row
Damage Zone: face-up Zerachiel, face-up Danielle, face-up Raguel, 2 face-up damage
This is a basic field set-up i thought of which is very pressurizing to the opponent, because if they let Asmodel hit, it will open them up to 2 more full strength attacks from Raguel, and Danielle later. Of course, it's risky to be at 5 damage in the current meta, so the part about Danielle is optional, and you can have one less face-up damage.
Here's a nice deck-list I thought up:
4 Zerachiel, 4 Malchedael
4 Asmodel, 4 Raguel, 3 Danielle
4 Aniel(pg), 4 Narelle, 4 Hesediel, 2 Nociel
Triggers: 4 Hot Shot Celestial, Samyaza(critical); 4 Rocket Dash Unicorn(critical); 4 Celestial, Landing Pegasus(draw); 4 Recovery Celestial, Ramuel(heal)
Starter: First Aid Celestial, Penuel
The reason I run Nociel in this build is to possibly swap Danielle or Asmodel into the damage zone, as well as obtain more shield for guarding during your opponent's turn. Hesediel serves as a good booster in the back row for higher powered columns. Narelle is a staple in practically every Celestial deck, because it has an on-call effect to allow you to swap cards from your hand with the damage zone, possibly setting up for more fun combos later. Penuel is still the best starter for the Celestials in my opinion because she allows you to superior call 1 unit straight from the damage zone for the effective cost of one counterblast(Asmodel & Raguel I'm looking at you :P).
Well, that's it from me for now for the Celestials. I run a Celestial deck myself, so I was able to write this nicely. Feel free to voice your opinions in the comments section though :D
