VRAINS anime series features Speed Duels, with the difference that Skills are special abilities of the Duelist that can be used in most situations but once per Duel, rather than cards that must be played during one's Main Phase (for example, the protagonist Yusaku can generate a random monster when his Life Points are below 1000)
In fact the printing of Unholy Heat (and to an extent Solitude) has mostly pushed out cards like Tarmogoyf out of the format, as the removal in the format is now so efficient that creatures either need to be one-mana, so you trade at an even level (Dragons Rage Channeler and Ragavan, Nimble Pilferer), too large to be killed by Unholy Heat (Deaths Shadow and Murktide Regent) or generate immediate value upon being played (Solitude, Fury and Omnath, Locus of Creation)
Une fois par tour, durant votre End Phase : retirez 1 Compteur de cette carte
That means your creatures won't naturally untap at the start of each new combat, but they will untap if one of your large creatures connects during any combat
Attach the targeted monster to 1 Rank 2 monster you control as material
banish all monsters on the field, until your opponent's 2nd End Phase
