There's been a lot of talk surrounding alumni as they have been very strong from a very long time. I've seen a lot of proposed solutions but I really dislike the idea of making the card gold or capping the value as the first one kills the card and the second only stops "win-more" greed decks. Here are my favorite nerf proposals listed from most important to least:
1) row lock patience (nullifies defender-vengeance abuse)
2) increase required patience for zeal (to 5 or maybe even 6)
3) alumni value shouldn't increase while on the board (lock in value upon deploy)
4) nerf inspired zeal (it outperforms the other leaders by a landslide)
5) increase provisions to 7 if the problem is still not solved (bone talisman is 7 so it's possible)
