Specifically with "Light and Darkness Dragon", you can perform a small lock using "Treeborn Frog". When "Light and Darkness Dragon" is destroyed, Special Summon this card with its effect. Since your field would be clear, Special Summon "Treeborn Frog" in your next Standby Phase, then use this card's effect to retrieve the Dragon. Tribute both monsters to Tribute Summon "Light and Darkness", allowing you to perform the same combo over and over again, provided that this card survives your opponent's turn each time. Having 1800 ATK and being Summoned after a situation where "Light and Darkness Dragon" has been face-up on the field, it's unlikely that your opponent would defeat this card easily.
You can use cards like "Honest" or "Hedge Guard" to ensure this card can survive your opponent's turn.
If you only have one card in your hand, this card on the field, and still have your Normal Summon for the turn, use this card's effect to discard your last card, retrieve "Swift Gaia the Fierce Knight" from your Graveyard, and immediately summon it via its effect, giving you an instant 2300 point beatstick.
You can create a revival loop using this card, "Arkbrave Dragon", and "Ruins of the Divine Dragon Lords"; by discarding "Ruins" to retrieve "Arkbrave", then use the effect of "Ruins" to return itself to your hand while putting "Arkbrave" in the Graveyard. During the next Standby Phase, the effect of "Arkbrave" will activate and Special Summoning a monster, and you can repeat this loop during your next following turns.
