Super cheap and super good. The way this deck works is by controling the board with your counterspells and other control spells until you can play your Guile and killing your oponent with his own cards that you can play for free. Now im going to talk about all the cards.
Counterspells.
This deck focusus a lot on counterspells becouse it combos with your Guile and becouse it makes you stay alive in the early and mid game. This deck has a total of 17 counterspells.
Mana Leak is one of the if not the best counterspell in modern becouse it only costs 2 mana, and becouse in the early and mid game it is almost inposible for your opponent to stop.
Remand this card is also one of the best counterspells in modern becouse it is a huage tempo swing, that is becouse it not only counters a spell, it also draws you a card. The only issue whith this card is that it returns the counterd spell to its owners hand but most of the time that is more than worth it. But the best thing with this card is that if you have a Guile on the board, it does not return the counterd spell to its owners hand becouse the effect of Guile triggers first. And you also draw a card!?!?!?! Best counterspell in this deck.
Rune Snag
Just like Mana Leak only a bit worse in the early game and a bit better late game.
Stubborn Denial This card is interesting becouse it is almost unplayable in most blue decks, but in this deck it is realy good becouse if you have a Guile on the board this is a 1 mana counterspell that cant be stopt so i recomand you put it in the deck.
Dispel This card is usualy used to make sure your Guile actualy comes in play becouse your opponent might have a counterspell
Other spells
Serum Visions best card draw spell in modern 4 of no questions asked
Vapor Snag this spell is rly good in the early game becouse it makes you stay alive aganst decks with scary creatures and sometimes it is not bad to draw it lategame so i play 4 of.
Other stuff
Plumeveil
i love this card. it is a 3 mana 4/4 flash flying defender. this card does the same thing that the rest of the deck does. it makes you stay alive in the early and mid game. The only down side is that it cant attack but we have Warmonger's Chariot to do just that
Warmonger's Chariot. plumeveil is bea.
Jace, Architect of Thought This card is rly good in this deck becouse it makes you stay alive aganst aggro decks with its +1, it draws you cards with its -2, and it is a win con if your Guile does not work 4 some weird reason with its -8.
Thats all hope you enjoyed ;P
