Editing Warhammer 40,000/9th Edition Tactics/Tyranids (section)

===Pros===
*You can partially change your chapter tactics equivalent before the game starts to better counter your opponent. You have to choose at the list building phase on matched play but it still gives a lot more flexibility then other armies.
*Amazing psychic powers at your disposal and many different ways, mostly involving neurothrope, to buff your casts.
*Tyranids power-crept ''hard'' with their new codex. 9th edition is full of killy options, with tons of AP and multi-damage options,  so the codexes that are performing the best are those that give you hard caps on avoiding damage, either through invulns, or (x) rolls of 1-3 always fail. 
*Your Monsters have been buffed to be tougher with more wounds, and their signature abilities have been made actually useful. Formerly useless units, like Tervigons and Maleceptors, can now find a place in your army.
*Tyranids now actually play like an army that's under the control of a single, dominant hive-mind, with Synergy between units being key in the new codex. Synapse has been overhauled and Instinctive Behaviour removed. Synapse range can be extended through other Synapse creatures, and Synaptic Imperatives encourage you to take a variety of SYNAPSE units to gain access to their respective abilities.
