Welcome to Gaia! ::

first off, Marshmallon is limited to one. secondly, since you're running LIGHT Fairy-types, a triple-pack of Honests is a must (they're now much easier to get with the new Twilight Packs) and if u can, try and find Archlord Kristya, now only is it a powerhouse, but it stops Special Summons and can be reused repeatedly, plus can fetch back Honest for more Fairy shenanigans. also, i'd recommend giving Beckoning Light a shot, it can help you get all the LIGHT monsters you need when you need it. lastly, try the old staples (MST, Heavy Storm, Torrential Tribute, Solemn Judgment, etc.), these should stabilize the deck into a working-class jewel. hope this helps =P

you're quite welcome, but have you actually read Archlord Kristya? once you have, you'll start drooling =P

Well, one of the 'Agent' cards has an effect that proves useful in a friends fairy deck, though I'm not so sure it's as useful here. It's attack power is equal to the difference in life points as long as it's user's life points are higher. I think it's a level three.

try taking out one of your Zeradius, it's not a wise idea to run more field searcher monsters than their specific field (excluding the ones that don't destroy themselves). Running 3 when you have only two Sanctuary's in the deck is just asking for a dead draw.

You don't have many targets for shining angel, so why bother when the ones you do have you don't want in attack mode, or are better if you draw them?

Replace scrap-iron scare crow with mirror force.
add a second bottomless.
take out sakuretsu armor and magic cylinder and add Two Dimensional Prison.
replace the trap Jammer, magic drain and Judgement of anubis with 3 dark bribe.
Magical Mallet is a minus one, replace it withg a second double summon.
Add a Majestic Mech Goyru for a beat down piercer.

That should put you at an even 40, and make the deck flow a bit better, as well as counter your opponant more often.

Plus, having three costless counter traps in the deck, makes your Harvest Angel of Wisdom more useful.

Trust me, never have more searchers than you have field spells.
also, dark bribe is a great card. it has no cost to activate, and negates BOTH spells and traps. So what if your opponant draws one card, chances are, you just negated a game breaker like mirror force or heavy storm with it.
Magical mallet can also give you dead draws too. but i can see where your coming from with it. if thats the case, take out a Joan so you have room for that extra double summon.
Goryu is a 2900 atk fairy Piercer that can be summoned with one tribute. after it gets sent to the grave by it's own effect (it's not destroyed like ohka for some reason), you can use athena to special summon it next turn.
