How can I fix being mana locked, My main lands base is green red, white, but I have other slivers I'm using that are not those. The only thing I have are 1 sliver hive, 2 promenade, and 1 manaweft I rarely get those first time to be able to play my gale rider or siphon early if I draw them, they would basically be stuck in my hand if I can't get one of those cards and I keep drawing red green or white mana all the time
