#1 Umbreon ex Art Rare This one is a little bit of a dark horse or maybe a dark chase but you can never count an Umbreon alt art out
1 P-214 P Digimon Lv.3 Alternative Art Betamon (X Antibody) Color Blue Cost 4 DP 3000 Digivolve Cost 1 Blue 0 from Lv.2 Form Rookie Attribute Virus Type Aquatic/X Antibody Card Text 1 [Special Digivolution Condition] [Digivolve] [Betamon]/[ModokiBetamon]: Cost 0 [Effect] Decode ([Betamon]/[ModokiBetamon]) [On Play] [When Digivolving] By placing this Digimon as the bottom digivolution card of any of your other Digimon with [Seadramon] in their texts, return 1 of your opponent's Digimon with as high or lower a level as 1 of your Digimon with [Seadramon] in its text to the bottom of the deck
Players would run this card alongside Cascade effects, Cascade into Valki and then actually play Tibalt, cheating in a seven mana planeswalker that could draw cards, remove dangers, and threaten an ultimate that would give you all the options you could possibly need
Also, its kinda amusing that he can kill every Daemon Primarch and Abaddon in combat
It can remove one permanent for each player, allowing you - for four mana - to deal with the biggest threats on board, and pick off a Sol Ring or two while you're at it
