A semi-budget Esper control deck for modern.
Early Game (1-2): Stall early using your Wall of Omens and Thing in the Ice as blockers while using Path to Exile and Condescend on anything that can threaten you through your walls while you develop your mana base and dig for your win conditions with spare mana. This is your weakest stage in the game, play cautiously and avoid doing anything reckless.
Mid Game (3-5): If possible try to flip Thing in the Ice for a free board reset, the earlier the better as it allows you to apply pressure and if your opponent doesn't have an immediate answer for it it can win you the game by itself. If that doesn't work, cards like Supreme Verdict and Silumgar's Command allow you to begin to reverse any gains in tempo your opponent may have made during the match (and Silumgar's Command can also kill any pesky planeswalkers!) so far while you get down Dovin Bann to lock your opponent out of the game almost completely.
Look to save Dissolve for anything Condescend and Silumgar's Command can't hit,its important to save it for very powerful threats due to it being the only general counter spell in the deck. Esper Charm is a great way to gain card advantage over your opponent either through draws or discards and can also hit enchantments in the rare case that is useful. Don't forget Shambling Vents are a nice way to gain back some lost life and act as last ditch blockers in a pinch.
Late Game (6+): This is where the real fun begins, as the game progresses you are going to get more and more mana to cast things like White Sun's Zenith and Sphinx's Revelation, both extremely powerful cards that can turn the tide of almost any game. In addition a powerful win con becomes available to you in the form of Sorin, Grim Nemesis, who can be extremely devastating to your opponent with his +1 or his ultimate.
At this point your opponent will likely be running out of cards and you should have anywhere from 3-7 cards left yourself. By now, so long as you are not almost dead you are basically guaranteed to win as you have everything you need to prevent your opponent from playing the game while you tick up your inevitable doomsday cards. Have fun!
