Collectible Card Game Headquarters

I'm updating mtg-cards-data.txt for today's spoilers.

New mechanics are:
Exploit - When a creature with exploit enters the battlefield, you may sacrifice a creature you control(including the one with the ability).
Formidable - Formidable is an ability word, so every formidable ability is different, but they all care in some way about controlling creatures with total power 8 or greater.
Megamorph - Like Morph, but as the creature is turned face up, it gains a +1/+1 counter. The addition of the counter doesn't use the stack and can't be responded to.

Returning mechanics are Rebound, Bolster, and Dash.

.

.

Working on rest of the white cards.

I noticed while implementing Gudul Lurker that the "~ can't be blocked" is still templated as "~ is unblockable" in the tooltip text, though that wording was changed with M14.

On Dragonlord Atarka, I am guessing I am using incompatible damage and targeting functions. It lets me target multiple creatures and planeswalkers, but not dealing any damage.

When Dragonlord Atarka enters the battlefield, it deals 5 damage divided as you choose among any number of target creatures and/or planeswalkers your opponents control.

Code: Select all

Ability ability = new EntersBattlefieldTriggeredAbility(new DamageMultiEffect(5), false);
ability.addTarget(new TargetCreatureOrPlaneswalker(1, 5, filter, true));
this.addAbility(ability);

On Sunbringer's Touch, my creatures don't seem to be gaining trample, or it doesn't show in tooltip at least.

Each creature you control with a +1/+1 counter on it gains trample until end of turn.

Code: Select all

private static final FilterControlledCreaturePermanent filter = new FilterControlledCreaturePermanent("Each creature you control with a +1/+1 counter on it");

static {
    filter.add(new CounterPredicate(CounterType.P1P1));
}

Code: Select all

Effect effect = new GainAbilityControlledEffect(TrampleAbility.getInstance(), Duration.EndOfTurn, filter);
effect.setText("Each creature you control with a +1/+1 counter on it gains trample until end of turn");
this.getSpellAbility().addEffect(effect);

You will need something like TargetCreatureOrPlaneswalkerAmount(). Try this code.

I found the problem. A fix is being submitted.

Can DamageAll not be filtered by AnotherPredicate? Or am I missing something else here? The card is not being generated.

I noticed some funny business with AnotherPredicate() also. I eventually just worked around it for Enduring Scalelord because I was about to throw my computer out the window.

I don't have any syntax errors on Harbinger of the Hunt, but I must have some little thing throwing it off, because it still doesn't generate the card, but I just made Scourge of Kher Ridges, which is basically the same thing, just with different damage amounts. It worked fine, even though I cut and paste the activated abilities and filters over from Harbinger. Also made Fire Ants without problem.

You have a spelling error in the mana costs:

Code: Select all

{3]{R}{G} instead of {3}{R}{G}

Shows it clearly in the server start log:

Self-Inflicted Wound Target opponent sacrifices a green or white creature. If that player does, he or she loses 2 life.

What's the best way to check to see if the player sacrificed a creature?
