Notably, this means other players can't try to remove Elves from the battlefield after you activate this ability but before it resolves
If you end up overcorrecting your deck with permission and removal spells instead of these creatures, you then run the risk of drawing these at the incorrect time (such as drawing Spell Snare against Sultai Reanimator)
Along with Ad Nauseam, Thassas Oracle, and Mana Crypt, Dockside is a card that practically screams cEDH
For as long as this creature remains on the battlefield, gain control of that permanent, it loses all abilities, and it can't attack or block
Personally, I play this card in Commander decks that care about manipulating the top of my deck
Dont forget were a creature tribal deck, so we need to max out on creatures and take fewer non-creature spells
