Once Per Turn Annoying xD

the point of it saying once per turn is using it onc e per turn... anyway if you can get that card out of th field and then get it back or sumon another you can use it again

Once per turn is a "What you read is what it is" type of effect. You can only use the effect of that card once per turn while it occupies that space. Lets say I have Lonefire Blossom. I tribute it to summon Gigaplant from my deck using it's effect. I then normal summon Gigaplant and use it's effect to special summon that exact same Lonefire Blossom. This new Loneife Blossom may now use it's effect once again because it is treated as a different Loenfire Blossom.

Now this is not to be confused with certain effects like Rescue Rabbit that say "You can only use the effect of ______ once per turn." If you see this you can't use another one's effect. Like If I use rabbit, banished it summon 2 monsters and then played Double Summon to summon a Tour Guide. Then I summon Leviar and Re-summon that Rescue Rabbit. Even though it is a "different" rabbit you may only use the effect of Rescue Rabbit once per turn.

Yeah I Know , I Mean if There IS Combos To Make ME USe it Twice
Like Book of Moon

book of moon is not a once per turn card... but same if you can get it to the hand then you can use it again.

if you are talking about using a once per turn effect then book of moon and summon it again to use its eff thne yes you can do it but u cant flip in the same turn its sumoned or flip summoned unless you use anothe card like book of eclipse, ou can use this cobo to.. idk, mill every card in yoiur pponen deck with morphin jar or that purple worm

there are certain Type or archtype specifics that can return to hand to then special from hand, so think of trying those out if u really want a re-enabler.

Well, what I've learned with power planner loop is, like what quincymccoy said, that some archetypes have a re-enabler.

So I wanted to make a competative Genex deck.

I was wondering about the role Birdman plays in the Genex Archetype. It hit me during the Power Planner loop.
Basicly, you normal summon Power Planner, get Birdman, summon Birdman by returning Power Planner and summon it again if you have Ultimate Offering. The cycle continues.

Most Genex (Ally) monsters, like Power Planner, have an effect that activates when normal summoned. Genex Ally Birdman lets you get one of those monsters back to be normal summoned again and let you have it's effect again.

Using this knowledge, you can try things like making an OTK deck using Brionac and Ultimate Offering or something.
