Bloodroot Apothecary is particularly effective in Commander formats due to the longer game lengths and the presence of many different strategies.
Here's how it can be utilized:
Poison Counters: Its toxic ability can be a significant threat, especially in decks that focus on accumulating poison counters. This can be combined with other cards that deal combat damage or generate poison counters, making it a potent threat. Proliferate is a prime example of a mechanic that allows you to choose any number of players or permanents with counters on them and add an additional counter of the same type to each, in this case poinson counters.
Treasure Tokens: The treasure tokens generated when Bloodroot Apothecary enters the battlefield can be used for various purposes, such as casting spells, activating abilities, or sacrificing for mana. This can help to accelerate your game plan or provide a valuable resource for your opponents.
Token Synergy: If you're playing a deck that generates a lot of tokens, Bloodroot Apothecary's ability to capitalize on opponents' token sacrifices can be a significant advantage. This can help to drain your opponents' life totals and put pressure on them.
Token Decks: Use Bloodroot Apothecary in decks that generate a lot of tokens, such as Skrelv's Hive and Kibo, Uktabi Prince. This will allow you to benefit from both the treasure tokens and the poison counters generated by opponents sacrificing tokens.
Control Decks: Bloodroot Apothecary can be used in control decks as a way to put pressure on opponents and force them to sacrifice tokens as the card Angrath's Rampage.
Bloodroot Apothecary is a powerful card, but it's important to consider its weaknesses. It is vulnerable to removal spells and can be difficult to protect in the late game. However, if used effectively, it can be a valuable addition to your Commander deck.
