"D/D/D Duo-Dawn King Kali Yuga" Rating Score by はやとちり

I feel like it's too underrated.
A D/D/D trump card that has both a containment effect that does not allow chains and a powerful sweeping effect against his Spell/Trap cards.
Executive Temujin allows him to X-summon unhindered by Spell/Trap cards.
It's a D/D designation, but since he's not a D/D/D designation, it's easier to get out than Darkness Hell Armageddon, which has similar characteristics in that it can use 《D/D Savant Thomas》as an X material.
The negate effect of the effect works not only with triggered effects such as Bottomless Trap Hole, but also with destruction resistance, so you can hit and defeat monsters that cannot be destroyed by battle or effects.
A particularly compatible card is 《Wonder Xyz》. If you X summon it during your opponent's turn, your opponent will be blocked from all effects on the field that turn, and will be unable to do anything.
The Storm effect is powerful already, but it can also free chain and destroy permanent cards with nasty orbital effects before applying the effect. Dark Contract is also attractive because it can be collected.
In addition, even without the X material, it has 3500 RBIs that can be dropped into GY, and if you revive it with Temujin etc., it will be very reliable in terms of RBI.
A card with no weaknesses.
