Good mana-fixing makes all of the decks in your cube better, including the aggressive ones. The amount of mana-fixing available does not change the relative risk of playing additional colors in a given deck
There are plenty of unblockable cards to make attacking easier and less risky
They are unlikely to fall into the cEDH meta and, therefore, can attack you on an angle that your deck is not prepared to compete with
This archetype contains one of the most expensive cards in the entire format, Roserade, so be mindful if you opt to go this way
