Thunder Dragon Knight, Zoras | The Narukami G-Unit!

Thunder Dragon Knight, Zoras

Stride (Release it when both you and your opponent have a grade 3 or greater vanguard!)-Stride step-[Choose one or more cards with the sum of their grades being 3 or greater from your hand, and discard it] Stride this face down card on your (VC).
[AUTO](VC):When this unit's attack hits a vanguard, your opponent chooses one of his or her rear-guards, retire it, you choose up to two cards from opponent's drop zone, and bind them.

I would say this G-unit is quite good for Narukami first G-unit. However, there are some weakness on this unit such as your opponent makes the decision on retiring their own rear-guard.

This G unit also can has advantage on fighting a Legion deck user for example, if the battle hits a vanguard, you may choose triggers from drop zone and bind them forever.

As the starter also can be very advantages when combo with this G unit.

[AUTO]:Forerunner (When a unit of the same clan rides this unit, you may call this unit to (RC))

Recommending this unit to put on left or right back rear-guard circle.
