Stride (Released when both players' vanguards are grade 3 or greater!)-Stride Step-[Choose one or more cards with the sum of their grades being 3 or greater from your hand, and discard them] Stride this card on your (VC) from face down.
[AUTO](VC):[Choose a card name "Marine General of Heavenly Silk, Lambros" from your G zone, and turn it face up] When this unit attacks a vanguard, if it is the fourth battle of that turn or more, you may pay the cost. If you do, choose up to two of your rear-guards, and [Stand] them. Then, if the number of face up cards in your G zone is two or more, the units that [Stand] by this effect get [Power]+10000 until end of turn.
I started Generation Stride with the money cards so going to do the same here.
Honestly though I don't really know what to say here that other's haven't said already.
Aqua Force is a clan that is about playing to a formation that wear down an opponent taking chunks out out of them little by little and then making big plays that reward you for having completed an attack in a given order. With units like the Assault series rearguards act as your primary battle enablers, among others, as you attempt 4 battles a turn. What Marine General of Heavenly Silk, Lambros does is allow you to follow up those four battles with up two additional attacks swinging for 2-3 stages each, alternately you can put all your fire power on a single column by re-stand both the front and back row of that lane. As a result of just how devastating this completed formation can be, if the first Lambros skill doesn't kill you, the second one will.
Of course being a gambit that requires rearguards, and specific ones at that, the best way to counter Aqua Force is going to be in control decks, However as control decks tend to be on the slower side, but not always, in anycase, Aqua Force is well equipped for dealing with control as it is highly capable of early rush, which is something that completely destroys the clan I've spent the last few weeks going over in detail, Dimension Police.
So an Abrasion deck leading into an aggressive finale, also the kind of support Aqua Force needed and a huge redemption considering the poor quality of their Legion Support. I'm look at you Blue Storm Dragon, Tetra Burst Dragon.
