If you were worried about safely tapping Kilo, stations, convoke, and untapping cards like Manifold Key and Unwinding Clock, can solve that problem
Its sorcery speed, so you cant pull a removal on an opponents turn, but when it comes to you, if you have the mana, you can get out of any bind with this card
But that doesnt mean theres not something to be gained by spending at least a little on a storage option
Evaluating and swapping packages rather than single cards keeps the deck coherent and makes upgrades or pivots (like moving toward cEDH) far easier
Let's say Do-It-Yourself Seraph has the text boxes of both Beast of Burden (power and toughness equal to the number of creatures on the battlefield) and Psychosis Crawler (power and toughness equal to the number of cards in your hand)
Griselbrand is banned for other reasons, of course, but the ability to draw that many more cards is what sets it apart in Commander
