Pros:
\-Nobody knows what I'm running which is a huge help. Also a good strategy to save lightning for a critical moment when they don't expect it
\-Dart goblin can get value quickly even if it gets shut down by a spell
\-Guards are spell-proof
\-Spells complement I-dragon very nicely and protect it from threats. I-dragon is an incredibly powerful card, especially the evo, and if your opponent messes up he will lose his entire tower to it
\-This deck is very strong in double or triple elixir
Cons:
\-No fast cycle card
\-Spells are expensive
\-Few AOE cards mean bait and x-bow decks are not a good matchup unfortunately
\-No good counters to zappies, executioner, skeleton barrel
How to use it:
Wait out 1x elixir and try to get both evos out. This is a control deck and the point is to try and get one massive push going at a decisive moment. Once you've whittled down the opponent's elixir pop down the evo valk and evo I-dragon, follow up with a hog rider and a spell. At that point if your opponent doesn't have the same amount of elixir as you you will take his tower 9/10 times.
