Mana Thieves of Oona, casual (Modern)

Aggro Faerie / Rogue, combo loop soft-lock, tribal control-counter

It's not a top-tier Faerie deck but it's really fun.
The main goal is to be able to start the combo-lock loop with one Quickling in game and two Mistbind Clique in hand on (opponent's) turn 4 as regularly as possible, the Faerie Seer and the Picklock Prankster being there mostly to this end.
The faerie Harbinger can help in later turns (she can fetch Bitterblossom as a tribal faerie enchantment as well), and the softlock is still possible with two Quickling and one Mistbind Clique but at the cost of 6 manas instead of 4 every turn.
Bitterblossom plus Oona's Blackguard and its discard effect alone can be enough to get the victory if you can control the board.
The Silvergill Douser and the Spellstutter Sprite are solid defensive tribal tools.
At first the boomerang were in the sideboard, but it's a powerful and versatile protection, you can also use it on your own creatures or remove your bitterblossom if you're short on life...
Depending on the "meta" in my house, I switch between Glen Elendra Archmage and Sower of temptation for the main deck and the sideboard. All-in on either side or one of each, I change every 2 months.
Oona's Prowler can easily turn into an annoying low-cost flying monster.
And finally the Scion of Oona doesn't need an explanation, obviously...
The cost in mana overall is cheap enough to play with 20 lands.
At least it is for me ^^

SIDEBOARD : I've added 3 Hibernation because within my "metagame" here with my friends there is a very strong Boggle deck.
Oona in case of mono-colored deck, and because she HAS to be here to overwatch operations, she's the Queen ;-)
Witchbane Orb in case of red and mill.
Bontu's Last Reckoning and Sower of Temptation against strong aggro/creatures.
Dismember for Indestructible.
Hero's Downfall for Planeswalkers.

There are a lot of different mind games and combinations, I am more a RolePlay Magic player than a Strategic one and I often say that my deck alone plays better than me ;-)

With the lands from the Lorwynn edition (those with the flowers) and the boomerang from the 7th edition this deck is the most beautiful EVER ;-)
