Template:Potion of Illusion strategy
Potion of Illusion is useful as a value generator for cards that do not rely on stats, such as Deathrattles, Battlecries and other miscellaneous effects. In Deathrattle decks, this card can be used to generate cheap copies of powerful death rattles which usually have a high mana cost, such as 
Plagued Protodrake, 
Sneed's Old Shredder or 
Scrapyard Colossus.
It can also be useful when you would like to have more than two -or one if legendary- copies of a given minion on your board, similarly to 
Barnes, 
Simulacrum, or 
Molten Reflection. Examples of interesting targets are 
Sorcerer's Apprentice, Malygos, Jandice Barov, Mozaki, Ras Frostwhisper, etc.
With two Sorcerer's Apprentices and two Potions of Illusion, it's even possible to set up for an infinite damage combo. Play the two Apprentices, then the Potion. Play the 1/1 copies then play the second Potion, getting four 1 mana Apprentices in hand. On the next turn, play Archmage Antonidas, 
The Coin (which can be generated by 
Licensed Adventurer and a cheap sidequest such as 
Elemental Allies or Learn Draconic), and the four Apprentices for unlimited 0-mana Fireballs.
