I worry that it may rely a bit too much on cards with a very high mana value, which can be a risk if your opponents play lots of counterspells and removal spells, but its hard to tell how itll actually work before having a chance to play it
Each creature with one or more counters on it can't attack you or planeswalkers you control unless its controller pays , where X is the number of counters on that creature
Traditional aggro backs up early aggression with more aggression
The downside of this card is that its only a temporary solution, but depending on how big the advantage is, stealing it may win you the game anyway
Theyre even often guarding something because they will capture allies as objectives
I thought Eternal Taskmaster would be good but it didn't last, simply coming in tapped was too much of a drawback for what that card offered
