You'll also get to make use of any enter-the-battlefield or death triggers those creatures feature (note, as Deadpool's ability is a replacement effect not a triggered ability, Deadpool enters with the text box he's stealing, so can copy ETBs)
You can cast a second copy of your instants and sorceries during your turn, which helps set up powerful combinations
The creatures pretty small, but sneak makes it easy to get the first trigger and start doubling up on artifacts, whether that means a surge of mana from a second Relic of Sauron or two finishers like Portal to Phyrexia and Cityscape Leveler
It may not warrant legal action, but it certainly doesnt inspire player confidence, either
If a creature you control being dealt damage causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time
Being around like-minded people who are interested in similar things to me, the independence of the job and not having someone breathing down your neck at all times
