Argenport Valks with Arach!

My attempt at finding a home for the wonderful synergy between Arach and Endless Steps. Endless Steps also works well with baby Icaria and West, as they are both two drops with flying and endurance, letting you attack on T3 and still protect the site. At that point why not try Valkyrie tribal? The benefit of going that route is access to the valkyrie-warp cards and relic weapons.
Unfortunately, those cards aren't very good. It is probably better to forgo the valkyrie tribal route and just play good stuff. Still, I wanted to put this deck out there. Comments, suggestions, and other Endless Arach brews are appreciated.
