black regenerate cards mtg in and remove it from combat.) Regeneration [Fifth Edition] Moderately Played

Legendary Creature - Human Druid Zirda, the Dawnwaker Companion Each permanent card in your starting deck has an activated ability

At a glance, this Astarion would be wonderful as a black-white mana Commander, particularly if youre keen to create a vampire-themed deck

You can also do this combo even better with any sac outlet (Ashnod's Altar) + Renata, Called to the Hunt or Master Biomancer + any persist creature (Woodfall Primus)

Mongrel is so good

A lot of random cards would just hit the table and end the game in short order

Replacement effects that modify the number of counters being placed on creatures you control, such as the effect of Branching Evolution, apply to this ability as normal
