Bug reports

Magarena indeed does not support a mana pool.
This is mainly to help AI. But I also like the game without it anyway.
Also discarding hand at end of turn is a rule not enforced.
Puxl might add that rule, but I would like it to be at least configurable.
You can read about the rule differences on the project page.

Possible bug AI attacks with Guardian of the Guildpack which has protection from monocolored so why can't I block with Raging Ravine witch is a red and green creature so multicolored?

[ubeefx]

That sounds like a bug, the multicolored flag is probably not set for Raging Ravine.
I will make an issue for it on project page.

These may not be bugs, I may misunderstand the rules.

I had a Savage Lands in play, and Rootbound Crag came into play tapped anyway.

I had some multicolored lands in play, and Jund Hackblade didn't get the bonus.

[ubeefx]

These are some interesting questions.

Rootbound Crag only comes into play untapped when you control a basic Mountain or Forest or one of the Ravnica dual lands, because only those cards have the requested sub types.

Lands are colorless in Magic. So a land that produces multiple types of mana is not multicolored. Dryad Arbor is an exception, it states that it is green. This is actually very important as a rule to let cards where colored permanents matter work.

To be specific, the color of a card is determined by its mana cost; lands lack a mana cost, which means they lack a color (this also, interestingly, prevents them from being cast, but you can still play lands because the rules allow it as a special action (which doesn't use the stack)). This can be overridden by any effect, from a CDA (like Dryad Arbor or Ghostfire) to a temporary color shift (like Thoughtlace).

Solemn Offering,I couldn't target my own artifact.

[ubeefx]

Due to the life gain it certainly makes sense that solemn offering can target your own permanents.
Disabling the legal target filtering in preferences and undo can help in such situations.

Is there no tie in magarena?magic?
I don't know how the rules are so here I go: I did lethal damage to AI but survived thanks to Platinum Angel.AI attacked then with a first strike creature and Platinum Angel I blocked Platinum Angel and killed it and so did to me AI's first strike creature so now we are bellow 0 in life since AI got the previous damage that Platinum Angel prevented,so how come AI wins shouldn't be a tie.

A video of last scene after the combat.

[ubeefx]

In Magarena there is always a winner, there are indeed no ties.
When both players go below 0 life, the one that is the least below 0 wins.
In this case the AI has -1 and you -9, so the AI won.
When player and AI would have both for instance -2 life, the player wins.

The computer damaged me with a creature using a Sword of Light and Shadow and chose not to return a creature from its graveyard to its hand, even though it had multiple creatures in its graveyard.

[LSK]

I can't cast Inspirit on an untapped creature.

[Huggybaby]

Couldn't sacrifice Cursecatcher to stop casting of Black Knight. I was all blue, nothing else was in play.

Cursecatcher can't counter creatures only instants,sorcery.
