Skrelv's HiveHow it works & interactions with other cards

Token Production and Toxic

At the beginning of your upkeep, Skrelv's Hive triggers, causing you to lose 1 life and create a 1/1 colorless Phyrexian Mite artifact creature token. These tokens possess Toxic 1, meaning that whenever they deal combat damage to a player, that player also receives a poison counter. Note that toxic is independent of the damage amount; even if the Mite's power is increased, it still only gives one poison counter unless it gains additional instances of toxic. Furthermore, these Mites are strictly offensive units, as they carry a restriction that prevents them from blocking.

Step-by-Step Upkeep Resolution

1. The upkeep phase begins and the triggered ability of Skrelv's Hive is put onto the stack. 2. Players may respond with instants or activated abilities. 3. As the ability resolves, you lose exactly 1 life. 4. Simultaneously, you create the Phyrexian Mite token. 5. Any 'Enters the Battlefield' triggers (like Authority of the Consuls) will then trigger based on the token appearing. The life loss happens regardless of whether you can successfully create the token.

Corrupted and Lifelink

The second ability of Skrelv's Hive is a static ability that checks for the Corrupted condition: an opponent having three or more poison counters. As long as this condition is met, every creature you control with toxic gains lifelink. This includes the Mites generated by the Hive and any other creatures with toxic you might have on the battlefield. This provides a crucial defensive swing, helping you recover the life lost during your upkeep while you continue to apply poison pressure.

Common Mistakes

A frequent misunderstanding is how toxic interacts with damage. Toxic does not replace damage; it happens alongside it. A 1/1 Mite deals 1 damage (reducing life) and gives 1 poison counter. Another common error is forgetting that the Corrupted bonus applies to all your creatures with toxic, not just the tokens from the Hive. Lastly, remember that the lifelink only applies if an opponent already has three or more poison counters; the damage that grants the third poison counter will not benefit from lifelink in that same instance because the condition wasn't met when the damage was dealt.

Interaction examples

Building the Swarm

Phyrexian Mite

During your first upkeep after casting Skrelv's Hive, you lose 1 life and create a 1/1 Phyrexian Mite. On the following turn, you lose another 1 life and create a second Mite. You now have two 1/1 attackers that can each give a player a poison counter if they go unblocked, though neither can stay back to defend you.

Managing the Opponent's Defense

Ghostly Prison

If your opponent has Ghostly Prison on the battlefield, you can still create your Phyrexian Mite tokens every turn with Skrelv's Hive. However, to utilize those tokens for victory via poison counters, you must pay {2} mana for each Mite you wish to attack with. The Hive provides the bodies, but the Prison taxes your ability to deliver the toxic damage.

Entering a Hostile Battlefield

Authority of the Consuls

If your opponent controls Authority of the Consuls, each Phyrexian Mite created by Skrelv's Hive will enter the battlefield tapped, preventing them from being useful for anything until they untap. Additionally, your opponent will gain 1 life each time a Mite is created, effectively negating the pressure of the 1 damage the Mite deals, though they still must worry about the Poison Counter accumulation.
