All fixed in f0ecd78

1- Still Oona's Blackguard causes rogues to enter the bf with counters while it's on the stack + now itself gets a +1/+1 counter on stack.
2- Also the other ability doesn't make player discard a card, whenever a creature you control with a +1/+1 counter on it makes combat damage to that player.That applies to Oona's Blackguard herself and any other rogue now.

Confirming these two bugs with Oona's Blackguard:

It gives itself a counter even if it's the first and only Oona's Blackguard in play.

Rogues with +1/+1 counters on them don't cause discard when dealing combat damage to a player while Oona's Blackguard is in play. The card highlights for you to click and resolve the effect, but nothing comes of it.

Fixed both in commit 6e4dd27.
