They don't give too much support to this archetype because there are many cry babies still whining about buster blader. Which is as bricky as it could be so... that's gamea comment section for you
...That comment makes zero sense. The Gaia the Fierce Knight archetype has zero relation to the Buster Blader one. (Beyond both being based on Yugi's cards and featuring Level 7 Warriors.)
Aside from Arisen Gaia (well, and Lord, which won't happen any time soon), we're not lacking any actual members of the archetype. Gaia Drake, Gaia Dragon, etc. aren't "Gaia the Fierce Knight" monsters.
I guess he says that's GameA comment for you, because plenty of people here are very dumb, and I mean very, very dumb.
For example, the person above assumes another person stated both buster blader and Gaia Knight archetypes are related. False assumptions again and again, yes, that's GameA for you. "Where the most clueless noobs always comment".
