You can banish 1 Level 5 or higher monster from your Graveyard; Special Summon this card from your hand, also you cannot Special Summon monsters from the Extra Deck for the rest of this turn.

  • Can be special summoned.
  • Reveals your opponent’s set cards.


  • Restricts you from using your extra deck for the rest of the turn.


  • Because your opponent cannot activate cards in response to Lucius’ effect, your tribute summoned monster will be protected from cards like Floodgate Trap Hole and Paleozoic Canadia. Additionally if your monster has an effect that activates upon summoning, it will be protected from cards like Forbidden Chalice.

Follow Up

After looking at your opponent’s set cards you can then appropriately use removal for problem cards. Use cards like Nobleman of Crossout or Nobleman of Extermination to deal with set cards. Use Anti-Magic Arrows or Hey,Trunade! to deal with battle phase Traps.

Thunder Dragon

Discarding Thunder Dragon is a good way of loading your graveyard with cost for special summoning Lucius while also thinning your deck.

Tribute Summon

Some monsters can destroy your opponent’s cards upon summoning. Use Lucius to tribute summon into them to know what you are destroying. Or to know what kind of monster you are attacking into and what backrow your opponent has in place.

So... is there a chance to see Caius in the game (just asking)?

Chance for Caius is there, but whether it will happen or not is a whole different matter.

Caius 100% confirmed
Tribute summons suck bad already in duel links so yeah it could be introduced or should be. Seeing as its a normal summon and theres no effective removal for the worse summoning condition

We should at least get mega monarchs, i honestly dont see how they can harm this game anymore than 🔥 burn and tilt decks

Have you played against full force monarchs in the tcg, is all tribute summon but they do it so often and efficiently it feels like special summon XD.

I personally believe they are going to bring Caius to duel links as well. Very soon.

I don't see how Caius is "pretty much confirmed". Lucius means literally nothing. We've had Escher for a year and a half, and don't have Mobius.

dont be so pessimistic, my friend. These guys, these duel links devs are kinda slow fellas bcuz they are always delaying releases. But I definitely think they are going to give us Caius. Awesome card but not too dangerous for DL.

...That isn't pessimism. That's a "there is no hint that Caius is coming whatsoever". I have no opinion on Caius one way or the other. There's just no HINT of its impending arrival, let alone it being "pretty much confirmed". It'd be like me saying Ancient Gear Hydra is practically confirmed. Except I'd have more credence in that case, since we at least know an Ancient Gear Structure is coming.

Also worth noting that both of the Vassals that DO have a corresponding Monarch in Duel Links were released alongside it, making Caius even less likely.
this card may be obtainable from Card Flip Campaign..

Trigger type quick effects are very logical.
What did you get? Were you able to get any stratos or adoration?
I just used Elemental hero Shining flare wingman
Honestly this cards is very bad, you can just summon a Blue Eyes with 2 cards in your hand and it...
