Hello everyone, I have some questions. English isn't my birth language so the rules aren't really clear for me. So firstly, I don't understand what they mean by " friendly creature" in the card "renewing fountain", do they mean all my creature except my mage? And if that is the case, for the "Eatherian Tree" does it affect all the creature in the arena (enemy and ally)?

Secondly, can I push the creature on the border of the arena? Or does it count as a lethal barrier?

Finally, for the "Gate to hell" do I have to be on the zone to open it? And if yes, does it attack me too? And can my creature summoned by the Pentacle appear at the gate?

Thank's
