To tell you the truth, this deck is my favorite because of the avatar holding a blaster or any other sort of gun just like 'The End'. When I first read the effect I thought it might be a huge cost but after a use for a while I found out it is great, because we have plenty of unflippers for 'Kagero'. This deck focus on power and to tell you the truth, you can basically added all these cards into 'Vortex Dragonewt' to make it even better. Of course I prefer 'Vortex Dragonewt' because I do not need to select a column to retire.
Three heavy counterblasts, but is it worth it? Here is my explanation, this card can be so and so because of counterblasts. Well then I found out there are certain unflippers which can be added into the deck to make three counterblasts to zero if you can manage it. So therefor I will not say three counterblasts is heavy for this deck. Well you could make three counterblasts to two counterblasts if your opponent have two or less rear guards on their field.
This is a unit that gains 3k extra power if you have a unit in the center column. We rarely seen these power up abilities, they either need a cost or they gain power through other methods, but not one Legion that can just gains 3k when it attacks in 'Perdition' so far.
This card reminds me of the counterpart 'Chain-attack Sutherland', if people remember when it gains 3k power when ever an opponent unit is moved to the drop zone during the main phase, but it is only an 8k beater. It was quite an beater back then when 'Kagero' was focusing heavily on retiring and powering up and not restanding the vanguard. Now there is an improvement of 'Sutherland' and that is 'Tarayev'.
I would say this card is suited for decks that only retires columns. Retiring individual cards will not make this unit effective since it only gains 5k power when a unit in the same column is retired on your opponent side and you need Legion. So the maximum power you can get with this unit is 10k power but 10k power is plenty enough especially when it comes to the last turn of the game or the constant use of this ability.
This unit has become one of the main unit in 'Breakdown Dragon' deck. When it comes to retiring columns with less cost needed this card do the job perfectly, and it is perfect to power up 'Tarayev' without the need to use 'Breakdown' ability. Yes 'Breakdown' is not the only unit that can retire columns so you can power up 'Tarayev' but this unit can only use it once and that is when this unit performs Legion.
