Two characters will be receiving a update with the upcoming Mind Gem Season: Mr. Fantastic (Reed Richards) and Sam Wilson (Falcon). Both of these characters are support characters that don’t see much play from the player base.
I don't know if Mr. F losing a true heal could be considered a buff.
Or keeping the stipulation of if paird with another FF member provides any additional benefit
Mr. Fantastic (Reed Richards) Update:Flexibility
The cost of this power has been reduced by one. The player chooses two basic tiles to be swapped. Before the tiles are swapped, they become fortified protection tiles. This allows you to make strategic choices while ensuring that you get to keep the protection tiles. The Stun remains a 3-Turn stun at power level 5.
Master of the Fantastic
The heal has been converted to a burst team heal. The amount of AP earned each time this power goes off has been increased to 3 as long as you have a member of the Fantastic Four on your team.
The cost of this power has been reduced by two, the Countdown tile is now fortified and the damage has been increased for making Red, Green, and Yellow tile matches.
