While the Jet Pack is active, Yuri will ignore any glass platforms, moving freely through them.
Yuri players often conceal their Mines inside hide areas in order to surprise enemies.
Deploy mines in high traffic areas, jump pad paths and platforms to make it difficult for enemies to manouver around the lane. Other good locations include the Worm button on Sorona or the Creep Releaser on AI Station 404.
Stacking mines on top of each other is a great way of stopping droid pushes and dealing heavy damage to careless enemies.
Yuri is good when paired with Leon, considering you can stack your Mines, and have him pull enemies into a stack of them. Likewise Skølldir's throw with the right spacing. This is usually enough for a kill. If the enemy happens to survive, use your laser to aid your buddy in getting the kill.
Much like default Warp Time, Flash Forward affects the speed of everything inside the bubble, including Yuri's own attack speed. Consider taking it if you are running a laser build focused on damage.
With your team nearby, use your flight and hide areas to sneak on your enemies and get Warp Time on all of them.
A common mistake done by many new players is to willingly step on mines in order to clear them for the rest of the team. It's very rarely worth the risk as they usually deal high damage (specially when stacked) and Yuri can quickly and easily replace them.
Mines make a beeping sound. Use that to know when you are close to one. This is specially useful against mines planted inside hide areas.
Keep in mind that mines deal damage in an area around them. You may still be hurt if a droid or friendly 'naut steps on them if you are too close.
Mobile minions such as bull and clones with Basic AI Chip can assist you in clearing mines, specially when they are stacked on top of each other. Splash Dash can also be useful due to the innate invulnerability.
When engaging Yuri in close combat, remember that he can lay a mine right on top of you, which will immediately explode.
