in their mana costs, use the value chosen for X to determine if the spell's mana value is the chosen number. For example, if the chosen number is 4, a spell with mana cost 
Talion, the Kindly Lord rewards knowing what the table tends to cast. As Talion enters, choose a number from one to ten. Whenever an opponent casts a spell whose mana value, power, or toughness matches that number, they lose two life and you draw a card. A well-chosen number can turn ordinary opposing development into repeated cards.
Small numbers often cover a broad range of inexpensive spells and creatures, but the right choice depends on the decks in front of you. Two might catch common interaction and small utility bodies; another number may suit a table full of larger creatures. You choose as Talion enters, rather than with a trigger that opponents can respond to after seeing the number.
A spell matching more than one of the listed characteristics still causes one Talion trigger for that cast. A creature with matching mana value and matching toughness does not automatically provide two cards. The ability also does not counter the spell, so your growing hand still needs actual interaction to address dangerous plays.
Blue-black control and Faerie decks can use Talion as a patient source of cards while leaving mana open. Flying supplies a modest combat presence, but the main value comes from surviving through several opposing turns. Protection and efficient answers help preserve the engine. Rather than building only around forcing a particular number, use Talion to reward a solid interactive plan and adjust the chosen number to the opponents you actually face.
