Although I love being able to play wraths and get much more card advantage, spot removal is important in commander. It is more often instant speed and allows you to deal with threats once they are attacking you or right before they gain hexproof or indestructible. It lets the treats stay on the board and attack other people until just the right moment (usually after Ruhan has attacked Justin 4 times in a row). My go to spot removal spells are typically STP, Pongify, and Go For The Throat, since I really value making maximum use of my mana and I hate keeping a bunch of mana open and then not using it. However, I am wondering now if it is better to play more flexible answers that allow you to remove many kinds of permanents at one time. Sometimes the most critical permanent you need to remove is not a creature and you might be better off with an utter end, mortify or puetrify instead of the creature only removal, even if they cost a little more. What do you guys think? Is it better to have lower costs or more flexibility? Is this meta-game dependent? How many fireballs do you think I can fit into my mouth at one time?
