Ultra Rapid Draw - Runeterra Labs

The Rules

Quote From Lab Description

A high-speed, high-variety fiesta of deeply discounted cards and fast thinking!

Something's gone very wrong with the Temporal Transducer, and the Lab looks… a little different.

This mode's even quicker than Quick Draw. Each round you get a new hand of heavily discounted cards, and 4 mana to spend on them! Think fast, choose carefully, and ask yourself: What would Urf do?


  • This game mode is very similar to the Quick Draw lab with subtle differences
  • Your mana will start with 4 mana crystals and full spell mana; you crystal count won't increment like in normal matches
  • You hand will be randomly-generated fleeting cards
    • You'll start the game with a mulligan of 4 cards, 2 additional cards drawn after the mulligan, and 1 copy of Prolong
    • When the round ends, you'll discard any unplayed fleeting cards (i.e., most of your hand) and draw 6 new cards
    • Prolong is a 0-mana burst speed spell which will remove Fleeting from a single card. You start the game with one copy and receive an additional copy at the start of every odd-numbered round.
  • The card costs work as follows:
    • Cards that would normally cost 0-2 mana cost 0
    • Cards that would normally cost 3-4 mana cost 1
    • Cards that would normally cost 5-7 mana cost 2
    • Cards that would normally cost 8-15 mana cost 3
  • Creating a exact copy of any card will reduce its cost again.
  • Anything that is based around a card's mana cost like Concurrent Timelines and Ethereal Remitter will use the reduced cost and should be avoided


This is a very RNG-centric lab geared towards winning quick or losing quick. Some games will simply be "low rolled" and unsalvageable. Here are a few secrets to helping you win the more competitive matches, though:

  1. Try to float spell mana when you can. Many games are decided by one player "popping off" when their able to use their spell mana to play a powerful series of cards in a single round
  2. Be very selective in how you use your Prolongs -- if none of your current options are great, don't be afraid to save it for a future round. Some good targets include:
  3. Warmother's Call and Feel The Rush are extremely powerful in this game mode and almost always worth playing
