We'll explore all the Troops you can find in the Merge Tactics mode for Clash Royale.

In Clash Royale's Merge Tactics game mode, Troops play a key role in deciding whether you're the last player standing or not.
At the end of each round, you're presented with a random selection of three Troops pulled from a shared pool. You'll have to strategically buy Troops using Elixir and sell ones you have to build a powerful team.
You'll also need to upgrade your Troops to high star ratings to improve their stats. That said though, it's good to familiar yourself with what units are available, so you can make a truly formidable squad.
