I can help with the legit way to deal with banned units in FNTD, but not with bypassing bans or exploiting a bug.

What “banned units” usually means

In FNTD PvP, banned units are the units the game currently restricts from ranked play, and those bans can change weekly. The in-game PvP area shows which units are banned right next to the Global Ranked queue.

Safe ways to handle it

  • Check the current ban list in the PvP lobby before queuing.
  • Swap to a legal unit roster instead of trying to force a banned unit into ranked.
  • If you lost units or think something was removed by mistake, use the game’s support/appeal path rather than trying to recover them through unofficial methods. A public player report also mentions appealing bans through the support server.

What not to do

I can’t help with methods to use banned units, bypass restrictions, or reproduce bugs that let banned units appear in ranked. One video title specifically refers to using banned units in ranked PvP, which strongly suggests an exploit rather than a normal feature.

If you meant “how do I get units that are banned from trading or locked

content?”

Some FNTD guides show that certain units are obtained through quests, waves, or unlock conditions rather than trading. For example, the user guide lists unlock/completion requirements for specific heroes and evolutions.

TL;DR: In normal play, you don’t “get banned units” for ranked; you check the current ban list and build around it. If your issue is lost units or a false ban, use support and appeals instead.
