Why 10 Avatars for your collection?

Gives you 10 effects that are mostly unique to Avatars
Forces your opponent to play differently due to your collection always being a factor
Because its cool :)

When should you put on your first mask [[Pathfinder]]?

Turn 3: If you played a 2 drop that can defend you from damage or if you do not have a strong turn 3 play such as [[Lugbog Cat]] or [[Order of the Sacred Oak]]
Turn 4: If your turn 3 minion is still alive or you have a strong defensive site upfront such as [[Thin Ice]] or [[Troll Bridge]]; you will be able to draw a spell this turn rather than a site if you transform to [[Pathfinder]]
Turn 5: If you are able to mask into [[Pathfinder]] and play a 2 mana spell
Turn 6+: Mask as needed or keep on using [[Pathfinder]]

Early Game:

[[Pathfinder]] - Almost always your first choice. Make sure you keep one void location adjacent (preferably left or right) for your first path. *NOTE: You are still able to use [[Imposter]]'s ability to Tap -> Play or draw a Site even while in [[Pathfinder]] because you gain the abilities and your base abilities are not replaced

[[Sorcerer]] - If you are damaged during [[Pathfinder]] phase, [[Sorcerer]] is your next generic value engine. You want to be at 5+ mana to consider using.

Late Game:

[[Archimago]] - The deck runs just enough magics that you can catch your opponent by surprise via the [[Archimago]] ability

[[Avatar of Earth]] - Allows you to either attack with [[Imposter]] if you are near an Earth site or even finish your opponent on Death's Door if you find yourself next to them

[[Avatar of Water]] - Gives you the ability to teleport to a location to use nearby effects such as [[Ring of Morrigan]], [[Pollimorph]], [[Mesmerism]], etc. or put distance from you and your opponent's threats

[[Enchantress]] - Allows you to animate your auras to relocate/attack while also animating your opponent's auras to either remove them or banish them if any part of them are in a void space

[[Ironclad]] - Primarily used while on Death's Door in order to increase your chances of survival

[[Realm-Eater]] - If you find yourself next to a key offensive/defensive/threshold site for your opponent such as [[Thin Ice]], [[The Void]], [[Temple of Maloch]], etc. consider eating it. *NOTE: You will remain Immobile if you choose to eat a site and are transformed out of [[Realm-Eater]] before digesting.

[[Waveshaper]] - Able to use defensively or when you want to tap down blockers

[[Witch]] - Use when you have plenty of cards in hand and you want to apply pressure to your opponent's life total. You want 6+ mana available to start tapping for your opponent to lose 2 life.
