Silverquill Influence (WB): Control the table by manipulating combat and encouraging opponents to attack elsewhere while you generate value and draw cards
These were released by Wizard of the Coast in 1998
Kaalia is a commander, almost never an inclusion in the 99, and being Modern-legal has meant nothing, she hasnt been featured in any Modern decks of relevance
Valgavoth, Terror Eater Valgavoth, Terror Eater is certainly powerful, but its difficult to judge how much
Upgrade 10 The last card I am adding also works with the +1/+1 counters theme
It has a splashy effect that is viable in no other format but Commander, and Scourge allows you to dabble in the politics of Commander games (unlike say, Thundermaw Hellkite who just Hulk smashes an unfortunate opponent)
