Dragon Attendant, Reas]
Kagero's Sentinel with the clan's Keyword attached to
it. Many of the Keyword Perfect Guards have a way to
call themselves back to the hand from the rearguard
circle, and this is no exception.
Looking at the whole Kagero cardpool, Reas' place is
more so in Blademaster's deck than anything else.
In any Overlord build, you're gonna need Protect
Orb Dragon's countercharging alongside Conroe, because
you only get full mileage out of Conroe on your Legend,
Ace, Great, or X restand effects. You also want to keep
your soul to use Tahr and The Legend.
For all you Seal Dragon hipsters (I mean that in the
most endearing way possible :>), you have units that
will unflip for you (like a certain card from G Set 7),
so you'll continue to use the Seal Dragon PG for
especial counterblast/soulblast reasons.
B) In Blademaster, you can safely go off of just using
two countetblasts to control your opponent, and
you have Dragon Knight, Nadel who
easily softens up retirement effect costs. (There's
also Dragon Knight, Nadim,
but he's an on-hit unflipper which is less reliable.)
Blademaster's best backup Grade 3 is Dragon Fang
Chain-shots, Sutherland, who we'll go into later. And
naturally, he's also meant to be ran with Reas.
Basically, use Reas when your deck is based around
Blazing, and you're running countercharge effects that
will compensate for not running Protect Orb.
Alternatively, if you're a budget player if you cannot
actually get Protect Orbs.
