the best of one piece tcg BOOSTER BOX such as Mihawk from OP01 and Doflamingo from OP04 Premium Booster Box PRB-02 One

Control decks do use tempo but a lot of it is reactive tempo such as Wrath of God

A pattern of cards has popped up in red cards that let you take a creature from your hand and put it on the battlefield, getting around casting costs and counterspells, though they generally have the trade-off of having to sacrifice that creature at the end of the turn

Otherwise, on our Time Walk turn, we drop our Tundra

Then when it ETBs, you can put any number of creatures from your hand to the battlefield

If box breaks are catching on, then more sealed product could be opened, leading to a reduction in supply (in tandem with the increased demand due to the popularity of box breaks)

The boost is a one-time deal, and if you have many creatures, it should be a good one
