BG Possessed OTK
This deck brought me to Godrank and is fairly easy to play, especially for an OTK-Deck. It can cope with pretty much everything (especially rushes) and will OTK your opponent nearly every game.
It can OTK with a Possessed Ursus on board.
To do so you'll need 4 cards and 8 faeria with a horsemaster or 9 with a grovecaller:
Enchant the Ursus, guidance or tiki, falcon dive it, making it a 20/9 and then either Charge 3 to face or grovecall to face. Use crystal flowers to remove taunts or blocking creatures if necessary. Experienced opponents will smell a grovecaller and block your forests around his orb.
Keep in mind while playing this deck:
Every 5th card is an enchantment and every 3rd card is an enchantment target.
Every 10th card is mobility, taunt, buff or even heal making it very good vs rushes as well.
YOUR WIN CONDITION:
Have an Ursus on board. Place a forest within 2 hexes of your opponent. If that is impossible, place your ursus in a way, that Charge 3 (inbetween wells) or a combination of both would allow him to attack your opponents orb. A lot of times you won't even need the full otk combo thanks to the snowball potential of the card. Your opponent will do a good job making your creature a 32/2 before you know it.
HOW TO PLAY THE DECK:
Board Control and steady pressure. Start off with forests by going to one side with a big creature, preferably(!) to the same side your opponent goes to and seek confrontation. Sturdy shell to the other side to double collect. From that point on you'll just need to control the wells keeping at least one big creature up. Place your Crystal Flowers to bait your opponent into fighting and try to protect them. Draw your win condition. Against rushes, collect from your wells, block the hexes adjacent to your orb and neutral your way into the immediate range of his orb. Place a forest. if your Ursus goes beyond 20 damage, grovecall him to victory.
Willow/Tiki/Sturdy is the best starting hand. It can do everything for you.
Always make sure to keep only 1 big creature, preferably Willow.
Another good hand is Ursus/Horsemaster/Enchantment for super early agression and contesting your opponent's collector (do it). It can snowball superhard, especially vs mono red or green.
Guidance = Tiki Caretaker = Gift of the Rakoa
Grizzly = Ancient Beastmaster
Sturdy Shells = Nobles
Crystal Flowers = Tossers = Frogify (Crystal flower is better to snowball and to OTK)
