To the poster above, the importance of speed comes down to how active your senders are as even a few seconds can mean the difference between getting into the next FAW or not given how quickly many of them disappear. By replacing one of your five damage/buffer cards with a healer, you are reducing your attack power by 20% (sorta), so your decks base reliability without a healer also has to be factored in, though this is going to vary wildly from player to player. Loosing 20% of a decks damage/speed for an increase in reliability that only helps when both the FAW procs their AoE and they happen to have a heal waiting on standby doesn't seem worth it to me for most decks.
