Every last one of the above creatures were good in limited, so having a creature which kills them all (and flanks itself to boot) would be considered gravy on the boat
#9 I hope it continues with the trend of last year's by containing decently playable cards Cosmic holo pumpkin Munki is best Munki Assuming no ex-es, SSP Gimmighoul, TWM Dreepy and Drakloak, DRI Marnie's Impidimp and Morgrem, SSP Eevee, and JTG N's Zorua would all be cool
With Sigardas Aid the card gains flash, and Puresteel Paladin allows you to re-equip it to another creature as well
They all have different rules and uses but a similar, easy-to-read layout
Given how much utility Commander decks often have in order to react to massive creatures and game-ending combos, a card with a high mana cost and additional setups like Jumbo Cactuar isn't the deadliest threat out there
