The New Lore Archetypes, "Snake-Eyes" and "Diabellestarr" are excellent 1st waves of support for their initial debut. Diabellestarr also works especially well as an engine in other decks, and has seen a lot of success in the OCG in combination with archetypes like Rescue-Ace. Diabellestarr the Dark Witch is a very well designed card, as it has a way to summon itself from your hand, can search out an archetypal "Sinful Spoils" Spell or Trap, and has a way to recur itself as well, all on a hard once per turn.
The Sinful Spoils cards are also pretty good, as "The Sinful Spoils Hunter Fiend" can search out Diabellestarr and has an excellent GY effect to recycle another Sinful Spoils card which draws you a card, as well as Sinful Spoils of Doom - Luciela, which can make a high level Spellcaster you control, like Diabellestarr, unaffected by other monsters' effects for the rest of the turn, and makes all monsters your opponent controls lose ATK equal to the targeted monster's ATK, and if any of the those monsters drop to 0 ATK because of this effect, they are destroyed, but your monster is sent to the GY during next turn's Standby Phase. However, if you did target Diabellestarr to active this effect, and did so during your turn, it would leave the field during your opponent's Standby Phase, allowing you to resummon Diabellestarr using its 3rd effect, which would let you set another Sinful Spoils backrow, allowing Luciela to be a very unique and versatile card. Sinful Spoils of Betrayal - Silvia is currently the only Trap that is a target for Diabellestarr, but it's not too bad, as it is a quick effect targeted negate, similar to the effect of Swordsoul Grandmaster - Chixiao, that you activate by sending a Diabellestarr monster from your hand or field to the GY, though it also has another good effect while in the GY to negate the effect of a card your opponent activates in response to a Diabellestarr monster or Sinful Spoils spell/trap, making it a decent target for Diabellestarr.
The other Sinful Spoil backrow directly support the Snake-Eyes archetype, like how The Original Sinful Spoils - Snake-Eye sends another face-up card you control to the GY to summon a Level 1 Fire monster from your hand or deck, and has a GY effect to recycle a Snake-Eye or Diabellestarr monster and add a Level 1 Fire monster from your deck to your hand. Oddly enough, this card is not archetype-specific, so you can actually search out other cards, like Jet Synchron or Kurikara Divincarnate, in addition to the small Snake-Eye monsters. Snake-Eye Excel has a similar effect to search out a Level 1 Fire monster, which can actually search out another copy of itself, and has a Spell Speed 1 effect to send itself and another face-up card you control to the GY to summon a different Snake-Eye from deck. Snake-Eye Oark can target one of your Level 1 Fire monsters that are banished or in your GY to either summon it or add it to your hand, and shares to the same effect of Excel to summon another Snake-Eye from deck. Snake-Eye Wight Birch can summon itself from your hand if you control a Fire monster, and can be searched out with Excel, and has a similar effect to Excel and Oark, but it is a Spell Speed 2 effect during your opponent's turn instead.
The last Sinful Spoils at the moment is Sinful Spoils of Subversion - Snake-Eye, which can target a monster to put in their owner's Spell & Trap Zone. This Synergizes well with the The Shrine of Serpentine Sight - Snake-Eye, their achetypal Field Spell, which puts a Snake-Eye monster from basically anywhere in your Spell & Trap Zone when it's activated, can summon a monster treated as a Continuous Spell in the Spell & Trap Zone to your field when your opponent summons a monster, and gives all Level 1 Fire monsters you control 1100 ATK. The boss monster of the archetype is Snake-Eyes Flamberge Dragon, which has an effect similar to Sinful Spoils of Subversion to place a monster the Spell & Trap Zone, and has a quick effect similar to The Shrine of Serpentine Sight to summon a monster from the Spell & Trap Zone to your field, and even floats into two Level 1 Fire monsters in your GY. The archetype also has a Trap card, in The Glaring Ruler Snake-Eyes, but the card isn't too good.
Overall, the support in the first wave for these decks are extremely competent. They are very fun to play with, and good to experiment with.
