Template:Spiteful Summoner strategy
This card is best used in decks with high-cost spells such as 
Twisting Nether, Mind Control and 
Ultimate Infestation. That way, the minion summoned is more likely to be more powerful. In this way, Spiteful Summoner synergizes well Mage decks focused around 
Dragoncaller Alanna.
When constructing a deck with Spiteful Summoner, it's crucial to include a small selection of high-cost spells, as any low-cost spells could accidentally be revealed and result in much less value. Good examples include a Druid deck with its only spell being Ultimate Infestation, or a Priest deck that only runs 
Soul Mirror, 
Free From Amber and Mind Control.
In Arena, even if your deck contains low cost spells, unless your deck contains no high-cost spells whatsoever, Spiteful Summoner is still worth the gamble as even a 3-cost minion would most likely be worth the cost of summoning Spiteful Summoner.
