Relentless Assault creates an additional combat and main phase only if it resolves during a main phase. - 2025-09-19 · Wizards of the Coast
A creature that attacks each turn if able must attack only once that turn. It is not forced into each attack that turn. However, a creature that attacks each combat if able must attack again if it can. - 2025-09-19 · Wizards of the Coast
If you manage to cast this during a main phase of your opponent's turn, that opponent's creatures will untap and that opponent will be able to attack again. It will not allow you to attack during their turn. - 2025-09-19 · Wizards of the Coast
