If this card is sent to the Graveyard: You can Special Summon 1 Dragon-Type monster from your hand. You cannot Special Summon monsters, except Dragon-Type monsters, nor conduct your Battle Phase, the turn you activate this effect. You can only use this effect of "Kidmodo Dragon" once per turn.
If Kidmodo gets destroyed during your opponent's battle phase, you can special summon Darkstorm from your hand, and normal summon it on your next turn. This will enable his effect so you can destroy all spell/trap card your opponent controls.
You can bring more Kidmodo in your deck, or use Dust Knight instead. Use the flip effect when it gets attacked instead of flip summoning this card, so you can still conduct your battle phase, or special summon other Dragon monsters.
These cards have effects that can discard Kidmodo Dragon from your hand which will trigger its effect to special summon a Dragon-Type monster from your hand. Vanguard of the Dragon increases its own attack by discarding a Dragon-Type monster from your hand. Divine Dragon Apocralyph can send Kidmodo Dragon to the graveyard then it can recycle it back to your hand. By discarding a card from your hand Tribute to The Doomed can destroy 1 monster in the field.
Summoning high level normal Dragon-type monsters can be a good option as well. Combine this with Champion's Vigilance so you can get an early control over your opponent's actions.
