In a "Blackwing" or "Winged Beast" deck, you can summon this card after using the effect of "Blackwing - Zephyros the Elite" to summon itself. This means you will have 2 level 4 winged beasts for an Xyz summon, without using your normal summon for the turn.
Alternatively, use "Blackwing - Blizzard the Far North" to summon a level 4 monster, then use the effect of Zephyros to return Blizzard to your hand, then summon "Guard Penguin" for 3 level 4 monsters. Alternatively, Blizzard can summon a tuner to allow the summon of a high level synchro monster.
Note that while you can use this card after your opponent's "Ring of Destruction" has resolved (assuming it resolved as chain link 1), you cannot use it after your own copy has done so. This is because the last thing to happen is Ring of Destruction inflicting damage to its controller's opponent, so while the opponent could activate "Guard Penguin" at that time, RoD's controller would miss the timing to do so.
