Challenge him to a normal duel
Choose a commander card from your deck and place it face up in your command zone
If the total mana value of the cards revealed this way is 7 or less, create a 2/2 pink Teddy Bear creature token
Furthermore, even though he is an effect that requires multiple decks to be stacked, he can only Special Summon from the deck, so the loss is large when drawing two or more cards, and the return is too small for that
Send enough Phalanx and Couse to GY and then Synchro Summon, a large number of monsters will line up on the field, and since there is no turn 1 limit, if you connect to continuous Synchro, Link 4 and his high-level Synchro Monsters will fill the board
It gives your opponents little to no breathing room, especially if you can power out something like Blightsteel Colossus early
