Ran into someone who wanted to rule shark in cardfight vanguard named "Landon".

Anyway we ran into the problem of this card, Ambush Demonic Stealth Rogue, Kagamijishi and his skill.

(VC):When your unit is placed on (RC), if the number of units you have with the same name as that unit is two or more, until end of turn, that unit gets [Power]+2000 and "[CONT](RC):This unit may attack from the back row.".

So this is how the turn played out:
I had Onifundou (FV) and Emissary crow to rearguard.
my vanguard was Yasuie. I stride to Kagamijishi
use Onifundou skill to superior call Lake diver. Used Lake diver's skill to superior call 2 more copies of him.
And called Fujino. From Kagamijishi's skill the laker divers that were superior called get 2000 power and can attack from the backrow.

So my field was looking like this:

Fujino (9000) Kagamijishi (26000) Emissary Crow (8000)
Lake Diver (9000) Lake Diver (9000) Lake Diver (7000)

He's telling me the lake divers that were superior called don't get the power boost and don't attack from the back row. His thought was common sense. I'm telling him read my Kagamijishi. When my rearguards are placed on the field if there is another unit with the same name they get +2000 power and gain the ability. And when do card games have common sense as a ruling..?

Not sure if he misread my card and maybe thought that when my stride unit was placed on the vg circle that the rearguards had to be out on the field already to get the ability. And I also looked up similar situations on cardfight wiki since there was no official rulings on bushiroad and since he didn't find an official ruling but a page on wiki he scooped (If he didn't I was, not going to spend 20-30 minutes arguing over this). Now correct me if i'm wrong but I played this right?

Snow Plow, Polaris

Great Nature / High Beast / Zoo

ACT [V]: Legion 21000 'Twin Brush Fighter, Polaris'.
ACT[V][Counter Blast 2] When this unit attacks a Vanguard, you may pay the cost. If you do choose two of your <<Great Nature>> Rear guards, stand it and those units get power + 4000 until end of turn, and at the beginning of your end phase, draw a card and retire that unit.
Auto[V]: When this unit attack hits a Vanguard, you may draw a card.

Dark Musketeer, Dahlia <<Reverse>>

Basically with Tachikaze, save your units in your hand until you have guarantee combos. They are all about short bursts to pressure your opponent, similar to Nova Grappler. Tachikaze isn't necessarily about full rushing because if your playing someone that knows what they are doing, they will take out troublesome rear guards. Your trigger line up is fine, I personally run stand triggers (6 stand, 4 draws, 4 heals, 2 crit) with my tyrannoquake deck. That way I get the most out of my units.
Your grade two line up is perfect, it's the exact line up I run in my Tachikaze deck.
Grade one line up, try this out if you'd like: 3 Gattling Arrow, 2 Gioconda, 2 Tri-plasma, 3 PG /1 QW, 3 Iguano corg, 2 Tyrannoblaze. If the limit break enabler isn't for you then take him out and you have two slots available for tech cards or a card you'd need.

Now combo wise here's my ancient dragon combos (I don't use Iguano corg that much except early game), and in my Tyrannoquake deck, I have Ancient dragon baby rex as my starter and I run Babysaurus for later since it only works while in legion which is late game. Babyrex guarantee's early game pressure. And I also run 1-2 Tyranno Legend.

Early game(assuming baby rex is starter and supporting vg), ride whatever card that DOESN'T retire for the +5000, call a unit to rearguard that gets a +5000 power from retiring(from your deck it's dinocloud / gattling arrow). Have the vanguard swing in supported by Babyrex generally they won't guard since it's early. You hit, now swing in at the VG and get the +5000 power, superior call tyrannoquake and attack. In this scenerio they will either take 3 damage (assuming they don't get a trigger), or use up valuable late game resources.

Main combo late game, after legion call Tyranno bite to rearguard, have a unit behind him, call a rearguard and have a unit support VG. First attack have Tyrannobite attack a rearguard - yes rearguard unsupported. Second attack have your tyrannoquake attack at vg use his skill +10000 power +1 critical. Have him retire Tyrannobite, use Tyrannobite's skill and superior call him back at standing. Hopefully you get a trigger and you can magic number Tyrannobite to take a bite at the VG. This is your main to go.

Another combo you could use is have night armor attack at vg use his skill retire iguanocorg thats behind the vanguard. Iguano corg's skill superior call him behind vanguard or rearguard (your choice), attack with rear and we will assume it's Tyrannobite or quake. Then have iguanocorg support Tyrannoquake and use his skill get rid of Tyrannobite/quake in rearguard for the +1 critical / 10000. If it's tyrannobite you have another attack right there for your triggers.

Here's a couple pictures if you couldn't understand what I was saying:
