Foretell W (As you draw this card, you may reveal it and pay W.)
When this card is foretold, target creature gets +1/+1 and gains flying until end of turn.
Quote from Harmlesshamster »I really wonder if the rules could be translated into a sort of programming language well enough for new players to understand it.
Quote from ReapThaWhirlwind »Absolutely untrue. If a player is forced to cast a spell, and the conditions for being able to do so are present (untapped mana resources), then the order of operations for doing that is a given for the effect.
That's exactly what the rulings would say for this card.
Quote from ReapThaWhirlwind »You seem to be missing the point here, in that this statement had nothing to do with how I feel personally feel about errata, but relates to the fact that we already have a catalog of printed cards that, "change the 'text' of target spell or permanent", and critically rely on errata to define what the term 'text' specifically means (referring to only what's in the "text box" itself).
Quote from ReapThaWhirlwind »Not sure what you mean by "rigorous mathematical definition".
This is not a matter of mathematics, it's a matter of English.
It's perfectly fine that way, and I don't see how this is any different, or less acceptable than that. It's even a little less ambiguous, as the term "matching even or odd" and "integer" gives clue to specifics.
Like a mana symbol, the term '+1/+1—or +1/+1 counter' is technically a "value", where the number symbol serves as an "identifier". However, unlike a mana symbol, since an actual number symbol (in plain text) is used here, it's at the discretion of developer to allow the effect to change the 'number symbol' of the 'text'. I did explain this in the opening post, that I was uncertain as to what combination of number words or number symbols this should be able to change. A colorless mana symbol might have a 'number symbol' or 'text' within it, but it's encased within an image, which totally separates it from a traditional number symbol or text.
Even with the number symbol within it, a colorless mana symbol is a symbol of its own, and needs to be identified individually (as a mana symbol) to be changeable. That's not the case here with number symbols that identify power/toughness altering counters. It's plain text, that technically moreso, should be viable for change with this effect.
Quote from ReapThaWhirlwind »I would also question how viable the wording composure is for, "increase or decrease a number by 2" even is. That's like‒super-way out of the ballpark for MTG. This is the most function way to fit the effect within the confines of MTG wording composure. The word "matching" isn't really a stretch by any logical means, imo. I don't even recall a card using that term. Let me look it up. Nope, the gatherer doesn't even come up with anything, so I think it's fair to say that the context is open to interpretation.
To address the +1/+1 counter question. Yes, it could change a +1/+1 counter to a +3/+3 counter.

"During your next combat phase, ..."
Quote from ReapThaWhirlwind »The way I've composed the effect, with "As this enters the battlefield", the card would count the number of lands you control while it's on the stack (before it comes into play) to decide if it inherits the mana ramp bonus or not.
It's also essential to the functionality to do it this way, as by opening up that interactivity with the charge counter, it makes the card more open to cheap exploits, which can detract from the aspects of challenge implemented here (to provide the central basis for fun in the game). The hard-coded functionality also intends to provide boundaries and restrictions, that must be entirely locked-off from exploit, for balance of the game (by preventing the aspects of challenge/boundaries/restrictions from being too cheaply bi-passed or hot-fixed).
...if it becomes a creature, it can still be destroyed by power/toughness modding effects.
