Gennai's Hatcher Leomon

Other Digimon you control have haste.
When Gennai's Hatcher Leomon enters the battlefield,
create two 0/1 green Digi-Egg creature tokens.
At the beginning of combat on your turn, if you control one or more Digi-Eggs, sacrifice an Egg,
then create a 3/3 green Digimon creature token.
