the heart sliver is a key creature here as you need haste for this to work

i'd find room for a basal sliver or 2 (the black sliver that sacsa slither for 2 mana). you need the queen, heart, gemhide and basal tap 2 slivers for any color mana, use the 2 mana to create a sliver token. tap the token for mana, then sack it for 2 mana, use the 2 mana to make another token u still have 1 mana left so tap the new token for 1 mana, make another token, sack the 2 tokens for 2 new tokens, tap and sac the tokens for 3 more tokens, infinate creature loop.
