Can I Survive My First Pokémon Omega Ruby Hardcore Nuzlocke?

In this Pokemon journey I try to overcome the Hoenn league under hardcore nuzlocke restrictions. 1. If pokemon faint they are done and cannot be used for the rest of the game. 2. No items in battle other than held items. 3. First encounter in each route that is not a duplicate. 4. Level cap at the next gym leader's ace. 5. Everything else included in standard nuzlocke rules.
