I was building dragon link with Orcust before, but since harp was banned, extending to Orcust is now very difficult. So I come with another gameplan, because Verte is like a new Knightmare Mermaid, means you can have it as plan B or C if your combo fails. Super consistent setup with many different extenders (so it doesnt matter if it hard once per turn since we're running many different ones). Combo is like regular dragon link, with little modification, like if we're playing in MR4, we need to pay attention for link marker for Dragun and Savage (summoning Savage first, then summoning link monster in another extra zone so we can open up for Verte then Dragun). Borrelend is also can target Silverrokket to snipe opponent Super Poly target like Starving Venom, Dragostapelia, @Ignister Golem, or even their primary extra deck monster.
You may ask, why
Chamber Dragonmaid? The answer is it's your second
Seyfert, making us playing 6 starters. Chamber searches Hospitality on summon (both normal or ss, so can work with Gateway Dragon, even better than normal summoning Seyfert and tributing itself), link off Chamber for Striker Dragon, use Hospitality ss Chamber from GY, and now you have free link 2 (Romulus or Beat Cop if locked into dark because Rokket Synchron or Tracer). Basic end board is to have Borrelend + Savage and/or Dragun depends on our hands. We play minimal Rokket monsters because the recovery aspect (follow up play) is relying on Dragun as we can easily summon the second one using Magicalized Fusion (searchable from Verte, a generic link 2) and Borrelend is a disruption by itself, no need to target a Rokket monster to disrupt.
Dragon's Mirror used to summon Borreload Furious as it can act as disruption or extender and even reviving our godly link 5 Borrelend (cant activate its effect, but we still have the passives like protection and atking all monsters each). I was playing Destrudo but changed it to Tempest, Dragon Ruler beacuse Verte needs a 2k LP therefore making you left with 2k LP after using both, even non OTK deck can kill you easily (can play Galactic Spiral Dragon too).
Pros: Ultra consistent board with backup plan if playing through handtraps, multiple negations, hard hitters with protection, Dragun can pop 2 non targeting destruction, can follow up with great play even after they break our board.
Cons: Still has no prevention to Kaijus, Sphere Mode, Lava Golem, Santa Claws etc. Sometimes opponent has multiple Super Poly target in their extra deck.
