Well as the resident D/D/D expert here on SDA, allow me to give my thoughts on the 3 new cards and how they affect the set overall:
D/D/D Oracle Overlord D’Arc
Level 7 DARK Fiend-Type Fusion Effect Monster
ATK 2800
DEF 2000
2 “D/D” monsters
(1) While this card is face-up, card effects that would inflict damage to you instead makes you gain that LP.
Well D'Arc is a very interesting Fusion as it helps negate burn damage, like D/D/D Leonidas, who summons himself when you take burn damage, heals you for what you lose, and negates all burn damage, and heals what you may take instead. Plus it is a pretty strong beater with that 2800 ATK all for the same cost as D/D/D Blaze Overlord Temujin. I like it a lot, yet Temujin is still a bit more useful in my opinion for the combos he and D/D/D Alexander pull
D/D/D Sniper Overlord Tell
Rank 5 DARK Fiend-Type Xyz Effect Monster
ATK 2300
DEF 2000
2 Level 5 monsters
You can also Xyz Summon this card by using a Rank 4 “D/D/D” Xyz Monster you control as the Xyz Material. (Xyz Materials attached to that monster also become Xyz Materials on this card.)
(1) Once, during a turn in which you have taken effect damage: You can detach 1 Xyz material from this card to target 1 face-up monster on the field; it loses 1000 ATK and DEF, and if it does, the opponent takes 1000 damage (This is a Quick Effect).
(2) If this card is sent from the field to the Graveyard: You can send 1 “D/D” or “Covenant” card from your Deck to the Graveyard.
This XYZ is pretty bad at face value. What with its effect of making a monster lose 1000 ATK and DEF and dealing 1000 damage all for the cost of 1 material and you taking your own burn from the Covenant cards. Overall I'd say it is about the same in terms of a risk factor with its rank 4 counterpart, D/D/D Caesar, where with Caesar you can summon back any number of D/D monsters destroyed that turn, but you take 1000 per on your Standby phase. If you run a D/D/D deck, I'd say run at the very least 1 copy for those moment you want to set up with the covenant, but do not have D'Arc or Leonidas
D/D Pandora
Level 5 DARK Fiend-Type Effect Monster
ATK 1700
DEF 2100
(1) When this card is destroyed by battle or your opponent’s card effect and sent to the Graveyard while you control no cards: You can draw 2 cards.
The most I can say about Pandora is it is a D/D Lilith with more ATK and a weirder eff. Lilith is more useful in my opinion cause she can grab resources from your grave or extra deck and put them to use in hand. Pandora should not really be bashed however. It is a good card if you can get it on field with D/D Proud Chevalier for any rank 5 plays you may want to make. Also the eff is useful if you are at the bare minimal of draws, like say you are topdecking and this and Cost Down are in hand. In a case like such, it is handy for grabbing more resources. Overall, a meh card
